Answers

Answer:

Hank is correct

Step-by-step explanation:

With parallel lines intersected by the same line, all corresponding angles are equal.  Also remember that the two angles the are formed on each line need to add to 180 degrees.  So we can take the two given angle: 7x+10 and x + 10 and add them.  x + 10 + 7x + 10 = 8x + 20 = 180

So Hank has the correct equation.

It’s hank I think but I’m not 100% positive tho

What is the range of possible sizes for side x?

Answer correctly and I will give you brainlist

Answers

0.5 < x < 16.5 given: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
Sum of any two sides > third side. (i)
Difference between the sides < third side. (ii)
If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.

Need help finding measurements on a rhombus

Answers

All of the measurements are the same because a rhombus is just a tilted square:
All sides are 4cm
Hope it helps ;)

Answer:

5. D  6. B   7. C

Step-by-step explanation:

All side lengths of a rhombus are the same therefore the length of WZ must be 4cm.

The sum of all the angles in a rhombus add up to 360 degrees, since we already have 2 100 degrees( opposite interior angles are the same) then the rest must be 80 degrees angles.

so, the answer is -4.

Answer:

-4°C

Key:

( | | ) = these in between numbers is the absolute value. EXAMPLE: |-8| = 8

Step-by-step explanation:

If it was -9°C and it INCREASED by 5°C, you need to ADD.

-9°C + 5°C

*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and  make it either positive or negative, depending on which absolute value is the greatest (|9|).*

-9°C + 5°C OR |9| - |5|

|9°C| - |5°C| = |4°C| = -4°C

(because the greatest absolute value, |9|, is negative, the answer is too.)
