Answer:
60° : 75° : 120° : 105°
Step-by-step explanation:
I like to work these by considering the relationship between a "ratio unit" and the angle it represents. Here, the sum of ratio units is 4+5+8+7 = 24. The sum of angles in a quadrilateral is 360°, so each ratio unit must stand for ...
360°/24 = 15°
Multiplying the ratio units by this value, we find the angles to be ...
(4 : 5 : 8 : 7) × 15° = 60° : 75° : 120° : 105°
1 1/100
.01 is the same as saying "one hundredth"

Because u subtract 35-10=? .The ? mark mean your other part to equal your amount
To solve the equation you can first subtract 4x from both sides. Then,
Since you arrive at something false, -5 is not equal to negative 8, so the equation has no solution.
