Answer:70 degrees and 150 degrees
Step-by-step explanation: The angles of a quadrilateral add up to 360. So the sum of the two angles is 360 - (55+ 85) = 220.
After that you can model the sum of the angles with an equation:
7x + 15x = 220
22x = 220
x = 10
then you plug in x for each angle 7(10) = 70 and 15(10) = 150
Answer:
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. the equation of the line is y = ½x + 6.

Answer:
$7,213
Step-by-step explanation:
The computation of the total earnings for June and July is given below:
For June
= $2,000 + 2.7% × $51,000
= $2,000 + $1,377
= $3,377
And, for July
= $2,000 + $68,000 × 2.7%
= $2,000 + $1,836
= $3,836
So, the total earnings is
= $3,377 + $3,836
= $7,213

Answer:
B) 18
Step-by-step explanation:
Perimeter = 2 + 2 + 1 + 2 + 1 + 2 + 1 + 4 + 1 + 2
= 4 + 3 + 3 + 5 + 3
= 7 + 8 + 3
= 10 + 8
= 18
<u>The correct option is (B) 18</u>
