Answer:
60° and 80°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Given 2 angles in ratio 3 : 4 = 3x : 4x ( x is a multiplier )
Sum the 4 angles and equate to 360
140 + 80 + 3x + 4x = 360, that is
220 + 7x = 360 ( subtract 220 from both sides )
7x = 140 ( divide both sides by 7 )
x = 20
Thus
3x = 3 × 20 = 60° and 4x = 4 × 20 = 80°
The angles are corresponding, and the lines are parallel. This means the angles are equal. What can you add to 53 to get 50°? -3.
Answer:
just subtract 150 from 180 and it will give you 30 so 30 is b
Step-by-step explanation:
I checked too because I added 30 plus 90 plus 60 is 180 and every triangle has 180 degrees and I got 60 from the angle on the right I assumed I was 60 since its smaller than the right angle.
Do u still have this homework or is it old
Answer:
(13y + 15) -9y
-117y - 135
Step-by-step explanation:
Distribute -9y to the inside numbers in the parentheses -117y and -135 are not compatible to each other ( because the -135 doesn't have a y ) so that would give you your final answer of:
-117y -135
