Answer:
m∠A=30°
Step-by-step explanation:
we know that
<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross.
Vertical angles always are congruent
In this problem
m∠A=m∠B ----> by vertical angles
we have
m∠A=x
m∠B=3x-60
substitute

Solve for x



therefore
m∠A=30°
Answer:
i think it is A
Step-by-step explanation:
sorry if it is wrong, have a nice day
Every time you see r, replace it with -3. Every time you see s, replace it with 5. You are working wth exponents, which means that the little number next to the big number (exponent) is how many times you multiply the big number by itself.
For example, 5^3=5x5x5=125 (isn't one of the problems you are trying to solve)
If the expodent is negative, then you divide. S<span>so if it's like 5^-3, you do 1 ÷ 5 ÷ 5 ÷ 5 = 0.008 </span>
Hope this helps! :)
