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°.

the correct answer is 5 6 and 7

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
