A straight line is 180°, so you can do:
109 + ? = 180 (? is the top angle of the triangle)
? = 71°
Because the triangle is an isosceles triangle, the other angle is 71° too.
71 + 71 + ? = 180
? = 38
You subtract 38 with 90 to find the other angle.
90 - 38 = 52°
To find ∠2 you subtract 52 with 180.
180 - 52 = 128
∠2 = 128
128 = 11x + 18
110 = 11x
10 = x
73/50
146/100
146%
The answer would be 146%
Answer:
Can't really expand x and 0, so I guess it would just be x * 0
Step-by-step explanation:
explained above :)
Answer:
Step-by-step explanation:
A) neither since the angles add to 179 deg.
B) neither since 63 + 47 = 110.
C) complementary since 61 + 29 = 90
Answer:
NO
Step-by-step explanation:
They are not the same shape. Thus, you cannot use a rigid transformation to get from A to B
