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
Answer:
2√3
Step-by-step explanation:
√2^2x3
√2^2 √3
2√3 (answer)
B, equal to because when you see the lines on the outside of any number, negative or positive, it's that number but positive. So now your expression is 8_8 and 8 equals 8. so your final answer is b, 8 is equal to 8
