1: 121, 2: 59, 3: 59
This is for the first graph because if you look at the bottom half of a circle is 180 so since one is 121 you just have to subtract 121 from 180 and you have your answer
X:2=24.3
x=24.3 • 2
x=48.6
Answer is 48.6
The answer is x= - 11/ 16
You can check this by plugging in x for -11/16
A and E I think because isosceles is two equal and one different and Right because it has a right/90° angle
Answer:
∠ A = 50°
Step-by-step explanation:
The angle adjacent to 145° inside the triangle is
180° - 145° = 35°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
85° is an exterior angle of the triangle , then
∠ A + 35° = 85 ( subtract 35° from both sides )
∠ A = 50°
