Answer: tbh i think 20
Step-by-step explanation:
Answer:
120°
Step-by-step explanation:
A line must add up to 180°.
The sum of angles in a triangle also adds up to 180°.
Step 1: Find measures interior angles.
3x = 180
x = 60°
Step 2: Find measures of exterior angels.
x + 60 = 180
x = 120°
It’s 144
You do a^2 + b^2 = c^2
B is 42 and C is 150 since it’s the hypotenuse
You do it all out and get 22,500 - 1764
Then find the square root and end up with 144
Answer:
6m + 2
Step-by-step explanation:
To simplify the expression you must have to use the distributive property:
(3m + 1)(2)
2 x 3m = 6m
2 x 1 = 2
6m + 2
