The property where you multiply ig
Answer:
145°
Step-by-step explanation:
There are a couple of ways you can get there:
1. ∠ACB is a right angle, 90°. Hence, ∠BAC is the complement of ∠ABC, so is ...
... ∠BAC = 90° -∠ABC = 90° -55° = 35°
Then, ∠BAC and ∠BAD are a linear pair, so total 180°. That makes ∠BAD the supplement of ∠BAC, so ...
... ∠BAD = 180° -35° = 145°
2. ∠BAD is the exterior angle at A for the triangle ABC. It will have a measure that is the sum of the opposite interior angles: given ∠ABC = 55° and right angle ACB = 90°.
... ∠BAD = 55° +90° = 145°
Answer:
B
Step-by-step explanation:
A radius is half of a diameter so multiply by 2
U know I can replace ur x and you won’t even know y boom
Answer: 98
Step-by-step explanation: you want to calculate the exponent first, so you use 7 * 7 = 49. Then, you use 49 * 2 = 98.
