The answer to your question is below
Step-by-step explanation:
I numbered the squares, see the picture below
Angle 3 and the angle given are vertical angles so they measure the same
angle 3 = 137°
The sum of the angles 1, 2, 3 and 137 equals 360°, so
angle 1 + 137 + angle 3 + 137 = 360
and angle 1 and 3 are vertical angles so angle 1 = angle 3
2angle 1 = 360 - 137 -137
2 angle 1 = 86
angle 1 = 86 /2
angle 1 = 43°
angle 2 = 43°
The angle given and the angle 5 are corresponding angles, they measure the same
angle 5 = 137°
Angle 5 and 6 are vertical angles, they measure the same
angle 6 = 137°
Angle 2 and angle 7 are corresponding angles, they measure the same
angle 7 = 43°
Angle 3 and angle 6 are corresponding angles
angle 6 = 137°
Angle 4 and 7 are vertical angle, so they measure the same
angle 4 = 43°
Equate what is inside cosine with , base period and solve for x,

Answer:
a = 3
Step-by-step explanation:
Calculate the distance d using the distance formula and equate to 4
d =
with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)
d = =
=
= a + 1 then
a + 1 = 4 ( subtract 1 from both sides )
a = 3
