The measure of the vertex angle of the isosceles Δ is 96°
Step-by-step explanation:
In the isosceles triangle
- Two sides are equal in lengths
- The angle between the two equal sides is called vertex angle
- The other two angles are called base angles
- The base angles are equal in measure
∵ The measure of one of the base angles of an isosceles Δ = 42°
- The base angles are equal in measure
∴ The measure of the other base angle = 42°
∵ The sum of the measures of the interior angles of any Δ = 180°
∴ 42 + 42 + measure of the vertex angle = 180
∴ 84 + measure of the vertex angle = 180
- Subtract 84 from both sides
∴ measure of the vertex angle = 96°
The measure of the vertex angle of the isosceles Δ is 96°

Answer:
The answer would be -10.
Step-by-step explanation:
It's -10 because -8-(-10) = 2
That is equal to -8 + 10 = 2 because two negative together make a positive number.
The volume of the resulting solid will be twice as large as the volume of the original solid.
Answer:I think the answer is 5/12.
Step-by-step explanation:
Sorry if I am wrong. :) but it should be correct.
He was camping at an elevation of 18,492
the following day, he descended (he came down) 2,516 ft....
so ur expression would be : 18,492 - 2,516 <==
and ur answer would be : The elevation of the 2nd campsite is :
15,976 ft <==
