Answer:
120 degrees
Step-by-step explanation:
Attached is a screenshot.
y = 180 - 50 - 70 = 60.
x + y = 180, so x = 120
Remember to try to use parallel lines when you can
The second uses the same method, just the opposite side.
Answer:
xy= 302,400
Step-by-step explanation:
You just have to find what x is. Pretend there isn't the signs and think of it as = signs. Then whatever u do on one side do it to all of them
The missing angles are the one with labels 1, 2, 3, 4.
180 = 43 + 69 + X
180 = 112 + X
X = 68 (1)
180 = 112 + 41 + Y
180 = 153 + Y
Y = 27 (2)
180 = 44 + 66 + Z
180 = 110 + Z
Z = 70 (3)
180 = 109 + 29 + Z
180 = 138 + Z
Z = 42 (4)
Answer:
3
Step-by-step explanation:
The left side of A is 1 unit
The left side of B is 3 units
The scale factor is 3
Check:
The top of A is 3 units and the top of B is 9
3*3 = 9
