two angles are supplementary. what are the measures of two angles if the measure of the first angle is 40 more than half the second angle

and

Step-by-step explanation:

Two angles that are supplementary mean that they both add up to 180°.

If one angle is 40 more than half the second angle then,

a = + 40

Both angles together would be:

180 =

Step 1 - Subtract 40 from both sides of the equation:

Step 2 - Multiply both sides by 2:

Step 3 - Divide both sides by 3:

Step 4 - Plug this into the original equation to calculate the angle:

Therefore the two angles are:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation
