Answer: m∠E=74\°

Step-by-step explanation:

1. By definition, the adjacent angles of a parallelogram are supplementary, they add up 180 degrees. Therefore, in the given parallelogram:

O+M=180

3x+1+2x+4=180

2. Then, you must solve for x, as following:

5x+5=180

5x=175\\x=35

3. Substitute the value of x obtained into 2x+4 to calculate the angle M:

2x+4=2(35)+4=74

Then:

m∠M=74\°

4. By definition the opposite angles of a parallelogram are equal, therefore:

E=M\\E=74\°

A.) 0.35x + 42 ≤ 70

She wants the truck for one day, which will cost $45. We don't know how far the truck is traveling so that is the variable. She cannot spend more than $70, since that is her budget.

b.) Solve for x using the above equation:

0.35x + 42 ≤ 70
0.35x ≤ 28
x ≤ 80

In a triangle, one of the angle measures 70°
Tanya [424]

Answer:

the two angles are 55° each

Step-by-step explanation:

Let the two equal angles be y each

Therefore,

70° + y + y = 180°

Collect like terms

2y = 180 — 70

2y = 110

Divide both side by the coefficient of y i.e 2

y = 110/2

y = 55°

Therefore, the two angles are 55° each
