The third angle in an isosceles triangle is 32 more than 2 times as large as each of the two base angles. Find the measure of ea
DIA [1.3K]

Answer: the third angle is 106 degrees.

The base angles are 37 degrees each.

Step-by-step explanation:

In an isosceles triangle, the base angles are equal.

Let x represent the measure of each of the base angles.

The third angle in an isosceles triangle is 32 more than 2 times as large as each of the two base angles. It means that the measure of the third angle would be

(2x + 32) degrees

The sum of the angles inna triangle is 180 degrees. It means that

x + x + 2x + 32 = 180

4x = 180 - 32

4x = 148

x = 37

The third angle is

2x = 32 = (2 × 37) + 32

= 74 + 32 = 106

Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles until he reaches a total of 26 m
sergejj [24]

Answer:

1.5x+12=26

Step-by-step explanation:  

Let x be the number of weeks that it will take Andy to reach his goal.

We have been given that Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.

Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.

1.5x+12=26

Therefore, the equation 1.5x+12=26 can be used to determine x, the number of weeks that it will take Andy to reach his goal.

Sasha does push-ups each day for five days. The numbers of push-ups she does each day or shown below.
lana [24]

The mean average of push ups Sasha does in 5 days is 26.2.

<h3>Mean average</h3>

  • Number of days = 5
  • Day 1 = 22 push ups
  • Day 2 = 36 push ups
  • Day 3 = 21 push ups
  • Day 4 = 25 push ups
  • Day 5 = 27 push ups

Mean average = Total push ups done / number of days

= (22 + 36 + 21 + 25 + 27) / 5

= 131 / 5

= 26.2

Therefore, the mean average of push ups Sasha does in 5 days is 26.2.
