A square has four 90° angles. So:
15x-30=90 add 30 to both sides
15x=120 divide both sides by 15
x=8°
Answer:
a = 36, b = 54
Step-by-step explanation:
Since the terms are in arithmetic progression then there is a common difference d between consecutive terms , that is
b - a = 72 - b ( add b to both sides )
2b - a = 72 → (1)
and
a + b - 72 = b - a ( subtract b - a from both sides )
2a - 72 = 0 ( add 72 to both sides )
2a = 72 ( divide both sides by 2 )
a = 36
-------------
Substitute a = 36 into (1) and evaluate for b
2b - 36 = 72 ( add 36 to both sides )
2b = 108 ( divide both sides by 2 )
b = 54
-----------------
Thus a = 36 and b = 54
The sequence is therefore 36, 54, 72, 90 , .....
Answer:
XZ = 44
KQ = 24
Step-by-step explanation:
XH is half of XZ, and XH is 22x so two times 22x will give you XZ.
XH times two equation - 2(22x)
XZ equation - 43x + 1
Set them equal
2(22x) = 43x + 1
44x = 43x + 1
x = 1
Put x in equation XZ
43(1) + 1 = 44
