<h3>
Answer: Choice B</h3>
Angle 1 = 147 degrees
Angle 2 = 80 degrees
Angle 3 = 148 degrees
======================================================
Work Shown:
(angle 1) + 33 = 180
angle 1 = 180-33
angle 1 = 147 degrees
---------------
Focus on the left most triangle that has angles 33 and 47 as interior angles. The missing angle is 180-33-47 = 100 degrees
The angle exterior to this 100 degree angle is angle 2
angle 2 = 180-100 = 80
We have enough info to conclude the answer must be choice B.
---------------
Let's keep going to find angle 3
The vertical angle for the 100 degree angle is also 100 degrees. This second 100 degree angle is part of the triangle on the right
This triangle on the right has interior angles 100 and 48
The missing interior angle is 180-100-48 = 32
The angle supplementary to this is 180-32 = 148, which is angle 3.
Answer:
x = 14; y = 8
Step-by-step explanation:
A perpendicular intersection means an intersection between 2 lines, forming angles of 90°. Then:
7x - 8 = 90°
11y + 2 = 90°
7x - 8 = 90
7x = 90 + 8
7x = 98
x = 98/7
x = 14
11y + 2 = 90
11y = 90 - 2
11y = 88
y = 88/11
y = 8
I hope I've helped you.
Answer:
25°
Step-by-step explanation:
2x - 5° = x + 20°
2x - x = 20° + 5°
x = 25°
Answer:
L/k
Step-by-step explanation:
If Tim has a wire that is L inches long and each piece is k inches long, then you would divide the total length by the length of each individual to get the number of pieces.
So,
L/k
