Y = 3 because in a rectangle, the diagonals are ALWAYS congruent. so you would have:
5y - 2 = 4y + 1
-4y+2   -4y + 2
y        =        3

Brilliant question!!!!
avanturin [10]

Answer:

a) 21

b) 78.5 - 28.3 - 12.57 = 37.63

Step-by-step explanation:

For the triangle, you want to use the formula 1/2 base times height and then subtract 2 time 2. For the circle, the formula is pi times the radius squared. Then, subtract the other circles using the same formula. I hope this helps! Please mark me brainliest because I have been scammed many times. Please and thank you.

Write an equation that relates the angle in a triangle. The measure of angle A is 45 degrees. The measure of angle B is b degree
Korolek [52]
Since the interior angles of a triangle equal 180°, then 180-45=135.

Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.

Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.

However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180
