Question

A quadrilateral has two angles that measure 30° and 90°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?

Answer 1

Answer:

ANGLE ARE 90 AND 150

Step-by-step explanation:

LET OTHER TWO MEASURE = 3X AND 5X

QUADRILATERAL SUM OF ALL ANGLE

30 + 90 + 3X + 5X = 360

120 + 8X  = 360

8X = 360 - 120

8X = 240

X = 30

NOW THE ANGLE MEASURE IS

3(30) = 90 AND 5(30) = 150
