Find a, b,x, y,z that's it

a= 31°

b= 59°

x= 87°

y= 93°

z= 63°

Step-by-step explanation:

5. start by looking at the right angle. a right angle is 90 degrees so you can subtract the given 55 to find the other angle in the triangle on the right side of 5. the smaller triangle must add up to 180 because all triangles equal 180. 180-86-35= 59. b=59°

now you can look at the angle that is on the left side of 86. these angles are supplementary so their angles add up to 180. 180- the given 86 is 94. now you can find a. 180-55-94=31. a=31°

6. you should find x first. 180-60-33=87. x=87°. now you can find y because y and x are supplementary. 180-87=93. y=93°. now you can find z. 180-24-93=63. z=63°

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
