Answer:
what the heck is that i rhink you mess up
Answer:
A
Step-by-step explanation:
if X is 7, and is connected/touching the three. You have to multiply and 7×3=21
Answer:
1
Step-by-step explanation:
It simplifies to 7^xy=7. That means that xy must equal 1 to make the equation true.
Answer:
The measure of Angle A is 45.5 degrees
Step-by-step explanation:
In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.
A + B + C = 180
2x + 4 + 3x + 5 + 3x + 5 = 180
8x + 14 = 180
8x = 166
x = 20.75
Now we can find the measure of Angle A by putting the value of x in for x.
2x + 4 = A
2(20.75) + 4 = A
41.5 + 4 = A
45.5 = A
