The measure of BD ≈ 5.36
<u>Step-by-step explanation</u>:
- The side BC = BD+DE+EC.
- The measure of BC = 20 and DE ≈ 9.28
- The angles ∠BD and ∠EC are both equal to 15°
- If the angles are same, then their sides are equal.
Let 'x' be the measure of BD and EC.
BC = x+9.28+x
20 = 9.28 + 2x
2x = 20-9.28
x = 10.72/2
x = 5.36 (approx.)
∴ The measure of BD ≈ 5.36
Answer:
You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.
Answer:
≈ 1.8 km
Step-by-step explanation:
150*5= 750 revs total
d= 2.5 ft
C=πd= 2.5*3.14= 7.85 ft
Distance= 7.85*750= 5887.5 ft ≈ 1.8 km
Answer:
27.3 yards
Step-by-step explanation:
Since this triangle is a right triangle, this can be solved using the equation:
a^2 + b^2 = c^2
c^2 is the side opposite to the right angle (37)
So, you need to change the equation to where it is set equal to b^2.
Subtract a^2 on both sides.
b^2 = c^2 - a^2
Now, plug in the numbers you have.
b^2 = 37^2 - 25^2
Simplify.
b^2 = 1369 - 625
b^2 = 744
Now, to find b, take the square root of 744.
√744 = 27.3
