One angle in a triangle is 100 degrees. the other two angles are congruent. what is the measure of one of the missing angles?
(a) 40°
(b) 80°
(c) 130°
(d) 140°

A

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

let x be the measure of the congruent angles, then

x + x + 100 = 180, that is

2x + 100 = 180 ( subtract 100 from both sides )

2x = 80 ( divide both sides by 2 )

x = 40

Thus the measure of one of the congruent angles is 40°

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.
