Mathematics

Idk for sure but x must be 90 since its half of the straight line which is 180 and the angles of a triangle must equal 180 when added so that makes the whole angle where y is 86 then divide it by 2 to get 43 for y

so x=90
and y=43

hope this helps :)

Answer:

U =35.5

Step-by-step explanation:

Since this is a right angle, we can use trig functions

tan theta = opp/ adj

tan U = 5/7

Take the inverse of each side

tan ^-1 tan U = tan ^-1 (5/7)

U = 35.53767779

Round to the nearest tenth

U =35.5

Wendy can wash a car twice as fast as Jason. When they work together, Wendy and Jason can wash a large van in 2 hours. How many
Ugo [173]
X= number of hours would it take Jason to wash the van by himself.
2x=number of hours would it take Wendy to wash the van by herserlf.

<span>we calcaulate the fraction of  work by Jason during one hour </span>

x hours-----------------------------1 work
1 hour----------------------   fraction of work during one hour.

fraction of work during one hour=(1 hour * 1work) / x hours=1/x


we calculate the fraction of work by Wendy during one hour.
2x hours-----------------------------1 work
1 hour----------------------   fraction of work during one hour.

fraction of work during one hour=(1 hour * 1work) / 2x hours=1/2x

We can suggest this equation:
2 hours(fraction of work by Jason during one hour + fraction of work by Wendy during one hour)=1 work

2(1/x + 1/2x)=1

least common multiple=2x
2(2+1)=2x
2(3)=2x
6=2x
x=6/2
x=3

answer: 3 hours would ti take Jason to wash the van by himself.

A = b(c + d) for b<br> Answer:<br> Written as an equation
madreJ [45]

Answer: B= A/(C+D)

Step-by-step explanation:

A = B(C+D)

Divide each side by B

A/B= C+D

Reciprocate both sides

B/A = 1/(C+D)

Now multiply each side by A

B = A/(C+D)
