In Triangle ABC, angle A measures 40 degrees. Give possible angle measures for B and C.

B = C = 70°

Step-by-step explanation:

In Triangle ABC, angle A measures 40 degrees.

We need to find the possible angle measures for B and C if ABC is in isosceles triangle.

For an isosceles triangle, two sides of a triangle are equal. We know that if two sides are equal, the corresponding angles are equal. Let equal angles are x. The sum of an isosceles triangle is equal to 180 degrees. So,

40 + x +x = 180

40 + 2 x = 180

2x = 140

x = 70 degrees

So, the possible angle measures for B and C is equal to 70°.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
