45+2a=180. You should always try to write down an equation for problems like these. Subtract the 45 to both sides of the equal sign. This gets you 2a=135. Divide the 2 on both sides and you get a=67.5 degrees. I hope that i helped, enjoy
6/10 and 12/20 are both equivalent to 3/5
Answer:
x=15 and y=49
Step-by-step explanation:
y+16=5x-10
and (y+16) + (8x-5)=180
so y=5x-26 and then
plug in for y so 5x-26+16+8x-5=180
that means x=15
plug in for x
y+16= 5(15)-10
that means y=49
thanks for the brainliest!

Answer:
x = 13
Step-by-step explanation:
<em>sqrt (x-4) + 5 = 2</em>
<em>The equation is √(x+4) + 5 = 2</em>
√(x-4) = 2 - 5
√(x-4) = -3
x-4 = (-3)²
x-4 = 9
x = 9 + 4
x = 13
Therefore, the second option x = 13 is correct.
