A. we know that cab is 35 degrees and b is 90 degrees. From this, and knowing that there are 180 degrees in a triangle, we can set up a simple equation.
180-90-35+ acb
b. so we know the measure of acb and acd will add to 180 and we also know acb from part a
180=acb+acd
c. We are given that D is 35 and B is 90. From this we know that 180-90-35 is angle A. We only want the cad part of angle A, but we know the other part cab. From this we know that
cab+cad=A
Answer:
length= 3.7 ft.
Step-by-step explanation:
T= (square root of length) * k
1.8 seconds = (square root of 3) * k
k= 1.8 seconds / (square root of 3)
a.) T= (square root of 11) k
substituting k:
T=(square root of 11) * 1.8 seconds / (square of 3)
T= 3.4 seconds
b.) 2 seconds = (square root of length) k
substituting k:
2 seconds =(square root of length) 1.8 seconds / (square root of 3)
Divide the equation by 1.8 seconds / (square root of 3):
2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)
10(square root of 3) / 9 = (square root of length)
square both sides:
100/7 ft= length
length= 3.7 ft.
Hope this helps.
Why on Earth would a realtor be selling shoes?
but srsly, 75% of 28 is 28*3/4 or 21. 28+21 is 49. he must sell them for$49.00 the pair
Answer:
<h3>
m∠A = 113°</h3>
Step-by-step explanation:
Vertical angles have the same measure
m∠A = m∠B
7x - 20 = 6x - 1
7x - 6x = 20 - 1
x = 19
m∠A = (7x-20)° = (7•19 - 20)° = (133 - 20)° = 113°
