Since b + 30 = 90, we know b = 60.
That means a = 60

a = 60
b = 60
c = 30

Answer:

a) 60°

b) 60°

c) 30°

Step-by-step explanation:

Get 60 by subtracting 30 from 90 because the angle is a right angle. Since b is identical to a and also is a right triangle, it will also be 60. Get c as 30 by looking at its vertical angle across from it.

Answer:

(x-5) (x-2)

Step-by-step explanation:

x^2 (-2x-5x) +10

basically you will write the equation down and then to double check multiply the x and then the -5 into (x-2). this can be repetitive if you get it wrong so try to do numbers that make sense.
