Find the measure of the indicated angle

76 =R

Step-by-step explanation:

Since the two sides are equal, this is an isosceles triangle.  The means angles S and T are equal.  We know that the sum of the three angles are 180 in a triangle.

R + S + T = 180

3x+1 + 2x+2 + 2x+2 = 180

Combine like terms

7x+5 = 180

Subtract 5 from each side

7x+5-5= 180-5

7x = 175

Divide by 7

7x/7 = 175/7

x=25

We want to find R

3x+1 = R

3(25)+1 = R

75+1 =R

76 =R

step-by-step explanation:

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
