(12, 12, 156) and (9, 9, 162)Step-by-step explanation:
Since AB = AC and the triangle is isosceles:
∠ABC ≅ ∠ACB3x² - 2x + 4 = 9x - 63x² - 11x + 10 = 0x = (11 ± √(121 - 4*3*10)/6x = (11 ± 1) / 6x = 2, x = 10/6The angles:
m∠B = m∠C = 9*2 - 6 = 12°m∠A = 180 - 2(12) = 156°m∠B = m∠C = 9(10/6) - 6 = 9°m∠A = 180 - 2(9) = 162°Related Questions
When y is directly proportional to x, the value of y = -2 when x = 4. What is the value of y when x = 8?
Answers
Answer:
y = -4
Step-by-step explanation:
When y is directly proportional to x,
= y ∝ x
= y = kx
Finding k
the value of y = -2 when x = 4
-2 = k4
k = -2/4
k = -1/2
. What is the value of y when x = 8
Finding y
y = kx

What is the portion if the base is 450 and the rate is 19%
Answers
Answer:
portion = 85.50
Step-by-step explanation:
[tex]Rate = (\frac{Portion}{Base})*100%[/tex]
Rate = 19%, Base = 450
[tex]19 = \frac{portion}{450} \times 100\\\\19 \times 450 = portion \times 100\\\\\frac{8550}{100} = portion \\\\portion = 85.50[/tex]

By what percent will a fraction decrease if its numerator is decreased by 50% and its denominator is decreased by 25%?
Answers
Answer:
it will decrease by 60% I think
Step-by-step explanation:
Lets use the example 100/100 and do the thing you get 50/125=40%.
Answer:
[tex]33\frac{1}{3}[/tex]%
Step-by-step explanation:
We can use a random fraction with numbers that make this problem easier to calculate. We can start with the fraction [tex]\frac{1}{1}[/tex] (1). If its numerator is decreased by 50% and its denominator is decreased by 25%(75% of it), the new fraction will be [tex]\frac{0.5}{0.75}[/tex] , which is the same as 2/3
The percent decrease from 1 to 2/3 is 33.333....% or [tex]33\frac{1}{3}[/tex]%.
You can use variables to solve this problem, but I find it easier to start with the fraction [tex]\frac{1}{1}[/tex] for calculation purposes.

The centre circle has a diameter of 3 cm and the difference in the radii of each larger circle is 4 cm. What is the circumference of the yellow circle? Use π=3.14
Answers
Circumference = 2×π× radius
Circumference = 2 × 3.14 × 3
Circumference = 18.84
Solution for the radius of a circle of radius 3 . I'm sorry if I made a mistake, I am not sure of the solution.
But is there a fee for the question?
These two laws can help you in the question:
Circumference = π× diameter of the circle. Circumference = 2×π× radius
The circumference of the yellow circle should be considered as the 18.84.
Calculation of the circumference of the yellow circle:Since
The centre circle has a diameter of 3 cm and the difference in the radii of each larger circle is 4 cm
So here the circumference be like
= 2×π× radius
= 2 × 3.14 × 3
= 18.84
hence, The circumference of the yellow circle should be considered as the 18.84.

Find the area. Round any decimals to the nearest tenth
Answers
Answer:
1.4
Step-by-step explanation:
Since we're finding the area, we need to multiply 1.2 times 1.2, which would give us 1.44, and since it says to round to the nearest tenth, we need to round it. If the number is 4 or under, we round down, if it's 5 and up we round up. In this case, we round down- so we end up with 1.4.

A = L x 4

In Circle P, EP = 2, PG = 12, and FP = 4.
What is the measure of PH?
A) 10
B) 16
C) 6
D) 8
Answers
Answer:
6
Step-by-step explanation:
FP * PH = GP * EP
If EP = 2, PG = 12, and FP = 4.
Then 4 * PH = 12 * 2
4 * PH = 12 * 2
step 1 simplify
4 * ph = 4PH
12 * 2 = 24
we now have 4PH = 24
step 2 divide each side by 4
4PH / 4 = PH
24 / 4 = 6
we're left with PH = 6
