29°
triangles can only have 180°
This is a right triangle, so one angle is 90°, leaving us with 90° left
90°-61°= 29°
It takes 7 hours to mow 4 lawns
Therefore every hour, (4 ÷ 7) or 4/7 lawns are mowed. This gives the rate.
For 35 hours, 4/7 x 35 lawns are mowed.
=35 ÷ 7 = 5
= 4 × 5
= 20 lawns
Answer:
<h2>
8:35 p.m</h2>
Step-by-step explanation:
An hour later (60 minutes) from 7:45 p.m. is 8:45 p.m.
Subtract 10 minutes from 8:45 p.m. to get 8:35 p.m., which is 50 minutes from 7:45 p.m.

1- Two times the sum of four and eight
2 x (4+8)
2- Seven less than eight
8-7
3-The product of x squared and thirteen
13x²
x = longer section
y = shorter section
x + y = 109
x = 2y + 10
so we sub in eq 2 into eq 1
2y + 10 + y = 109
3y + 10 = 109
3y = 109 - 10
3y = 99
y = 99/3
y = 33 <=== shorter section is 33 cm
x = 2y + 10
x = 2(33) + 10
x = 66 + 10
x = 76 <=== longer section is 76 cm
