Let ∠1, ∠2, ∠3, and ∠4 have the following relationships. ∠1 and ∠2 are vertical angles.
∠3 and ∠4 are right vertical angles.
∠3 is adjacent to both ∠1 and ∠2.
What is the sum of the measure of ∠4 and the measure of ∠1 minus the measure of ∠2?

i swear im abt to go crazy- math sucks :)

90°

Step-by-step explanation:

Ok, I get it now.

Draw two perpendicular lines. Starting at any of the right angles, name them 1, 3, 2, 4 going around in order.

Now you have vertical angles 1 and 2, vertical angles 3 and 4, and angle 3 is adjacent to angles 1 and 2. this is exactly what the description states.

Since angles 3 and 4 are right angles, then all angles are right angles.

m<1 = m<2 = m<3 = m<4 = 90

m<4 + m<1 - m<2 = 90 + 90 - 90 = 90

90°

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
