How many degrees is angle y

Answers

Answer:

y = 39°

Steps:

w = 180 - (85+42) = 180 - 127 = 53°

y = 180 - (88+w)

y = 180 - (88+53)

y = 180 - 141

y = 39°

Answer:

y = 39

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of both triangles , then

x = 42 + 85 = 127

and

y + 88 = 127 ( subtract 88 from both sides )

y = 39

A person hikes 4 miles in 2.5 hours. Find the unit rate in miles per hour.

Answers

Answer:

B) 18.8 cm
C) 37.7 cm
D) 75.4 cm

Answers

Answer:

B. 18.8cm

Step-by-step explanation:

Circumference = π x Diameter

The given diameter here is 6cm and we need to use 3.14 for π so:

Circumference = 3.14 x 6

Circumference = 18.84 = 18.8 (1.d.p)

Therefore B is correct.
