There are two equal sides of 10, which means this is an isosceles triangle. With an isosceles triangle, there are also two equal angles (25° each in this case). If angle D equals 25°, then angle F also equals 25°. Subtract angles D and F from the total degrees in a triangle.

Triangles Degrees= 180° total

Find angle E:
= total triangle degrees - < D - < F
= 180° - 25° - 25°
= 130°

ANSWER: Angle E is (B) 130°

Hope this helps! :)

The sum of two numbers is 65. The larger number is 5 more than the smaller number. What are the numbers?

ipn [44]

Answer:

30 and 35

Step-by-step explanation:

Put this question into equation form:

Let x be the smaller number, if the larger number is 5 more and the total is 65:

x + 5 + x = 65

2x + 5 = 65

Subtract 5 from both sides

2x + 5 - 5 = 65 - 5

2x = 60

Divide both sides by 2:

2x ÷ 2 = 60 ÷ 2

x = 30

As the larger number is 5 bigger:

30 + 5 = 35

So the two numbers are 30 and 35.

Hope this helps!

Answer:

51 minutes.

Step-by-step explanation:

We have been given that for every 15 minutes of a show, there are two minutes to commercial. At this rate, Leila has seen 45 minutes of a show. We are asked to find the time for which Leila has been watching TV.

We will use proportions to solve our given problem.

$\frac{\text{Minutes of TV show + Advertisement}}{\text{Minutes of TV show}}=\frac{15+2}{15}$
