Sum of three angle of triangle is 180

2y+20=100
2y=80
y=40

The explanation for this would because because the two base angles of an isosceles triangle are equal so since the both equal to 40 degrees, in total would be 80 degrees.

Since the total degrees of a triangle is 180 and you know the base angles make up for 80 percent you subtract that from the total of the angle your trying to find, which is 2y+20.

PROVE THE base angles of an isosceles triangle are congruent

Leno4ka [110]

You could use the isosceles triangle theorems. if two sides of a triangle are congruent, then then angles opposite those sides are congruent. so if the two sides of the triangle are congruent (which they should be if it’s an isosceles triangle) then the isosceles triangle theorem proves that the base angles are congruent

Keith_Richards [23]

Answer:

0.25

Step-by-step explanation:

Givens

orange: 75

Blue: 62

Green: 52

Red: x

Total: 252

Equation

75 + 62 + 52 + x = 252 Collect the like terms on the left.

Solution

189 + x = 252 Subtract 189 from both sides

x = 252 - 189

x = 63 Red Ones

Probability

P(Red) = 63/252

P(Red) = 0.25

The sum of 3 numbers is 127. The second number is 4 times the third. The first number is 5 less than the third. What are the num

Svetlanka [38]

The three numbers are: 17, 88 and 22

Step-by-step explanation:

We need to find three numbers.

Let Third number = x

Second number = 4x (given in question: The second number is 4 times the third)

First number x-5 (given in question: The first number is 5 less than the third.)

And We are also given in question that:

The sum of 3 numbers is 127. i,e

$x+4x+x-5=127$

Solving and finding x,

$6x=127+5\\6x=132\\x= 132/6\\x= 22$

So, third number x = 22

Second number = 4x = 4(22) = 88

First number = x-5 =22-5 = 17

SO, the three numbers are: 17, 88 and 22
