Answer:
1
Explanation:
−((10)(2)−(2)(8)+(5)(−1))
= −(20−(2)(8)+(5)(−1))
= −(20−16+(5)(−1))
= −(4+(5)(−1))
= −(4+−5)
= −(−1)
= 1

Multiplying two negative numbers would always give you a positive product
Example 1) -2 * -1 = 2
Example 2) -5 * -4 = 20
Example 3) -10 * -3 = 30
we know that
Two angles are Complementary when they add up to
degrees and two angles are Supplementary when they add up to
degrees
f the exterior sides are opposite rays, then a straight line forms and you have the two angles add to
degrees
So
the angles are supplementary and not complementary
therefore
the answer is the option
Never

5.
So, a is equal to 4x-16 which is equal to 2x+4
4x-16=2x+4
-2x -2x
2x-16=4
+16 +16
2x=20
x=10
2(10+4)
2(14)
a≈28
4.
a is equal to the angle next to h, and they’re supplementary angles so they add up to 180
28+h=180
-28. -28
h=152
6. angles a and d are supplementary angles
7. vertical angles !
8 *6= 42 so it gotta be bigger than 42 and 42 divide by 2 is 21 and 42+21= 63 you got your answer.
