Step-by-step explanation:
Given that,
X = 7x+5
Y = 9x-7
W = 112°
V = 90°
We need to find the measure of each angle. We know that the sum of angles of a quadrilateral is equal to 360°.
7x+5+9x-7+112+90 = 360
x = 10
So,
X = 7x+5 = 7(10)+5 = 75°
Y = 9x-7 = 9(10)-7 = 83°

??????????????????
Step-by-step explanation:
Amount of money spend in 1 day = x
So, amount of money spend in 7 days = (7x)
⇒ Amount of money spend in 1 week = (7x)
Amount of money saved in 1 week = y
∴ Income in 1 week = (7x + y)
So, income in 3 weeks = [3 x (7x + y)]
= (21x + 3y)
Step-by-step explanation:
The sum of complementary angles is 90°,
Let 1st be 30x then other is 5x,
30x+5x=90°
➡️ 35x=90°
➡️ x=90°/35=(18/7)°
THUS THE FIRST ANGLE =30*18/7=540/7°
AND SECOND =5*18/7=90/7°
