Answer:
h = 590
Step-by-step explanation:
To find x, rearrange the equation to where h is on its own side.
<u>Rearranged equation:</u>

Since 169 added to h was to find 769, 169 subtracted from 759 represents h.
<u>Solve:</u>

590 = h.
Answer:
a equals 105°
Step-by-step explanation:
angles in a straight line add up to 180°
a+75=180
a=180-75
a=105°
0.5 x 1/10 = 0.05 All you do is multiply
Answer:
25 and 54
Step-by-step explanation:
(a)
6z² - 2z + 5 ← substitute z = 2
= 6(2)² - 2(2) + 5
= 6(4) - 4 + 5
= 24 - 4 + 5
= 20 + 5
= 25
(b)
64 - 5z ← substitute z = 2
= 64 - 5(2)
= 64 - 10
= 54
