HELP! will mark branniest answer if right!

64 i think

Simple explanation:

find the missing angle of the triangle with two given angles:

add 36 and 84 to get 120

subtract 120 from 180 and you will get 60

subtract 60 from 90 to find one of the angles in the other triangle

so now you have that the other triangle has an angle of 86 and another angle of 30

add 86 and 30 to get 116

subtract 116 from 180 to get the "? angle"

you should get 64

Another possible explanation:

extend the line that contains the degrees 36 and 84

this will make a third, smaller triangle

this triangle has two measure that are easy to find and that is 96 and 54

when you add those together, you get 150

subtract 150 from 180 to get 30

30 degrees is the measure of the smaller angle at the 90 degrees symbol

now add 30 and 86 together to get 116

subtract that from 180 to get 64

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!
