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
That would be b

- - He runs 1.5 meters each second.
- Solve:
Divide 30/20
<span>=1.5
</span>To answer this we will divide the amount of meters by the amount of seconds. Then your answer will be the amount of meters Earl runs per second. Then we will check our work. Lets do it:-
30 ÷ 20 = 1.5
1.5 meter per second.
CHECK OUR WOK:-
1.5 × 20 = 30
<span>We were </span><span>RIGHT!!
</span><span>So, </span><span>1.5 meters per sec.</span>
Answer:
900cm^2
Step-by-step explanation:
24, 10, 30 in half= 12, 5, 15 so, 12*5*15=900cm^2
