Answer:

7. x= 100 8. x= 40 and 9. x= 74

Step-by-step explanation:

x + 45 +35=180(sum of angle of triangle )

or, x+ 80=180

or, x=180-80

or, x=100

same process as above for all

Find the missing side length, and enter your answer in the box below. If
Savatey [412]

The missing side length is c = 25 units.

Step-by-step explanation:

Step 1:

The given triangle has a 24 unit long adjacent side and a 7 unit long opposite side.

As we have two sides of the triangle, we can solve for the length of the other side by using Pythagoras' theorem.

The length of the hypotenuse is given as c units.

Step 2:

According to Pythagoras theorem,

c^{2} = 24^{2} + 7^{2} = 576 + 49.

c^{2} = 625, c = 25.

So the missing length, c of the given triangle is 25 units.

2x+2(1960/x)=200 please help for math hw
sp2606 [1]

Two solutions:

1. x =(100-√2160)/2=50-6√ 15 = 26.762

2. x =(100+√2160)/2=50+6√ 15 = 73.238

A slide 4.4 m long makes an angle of 33 with the ground. How high is the top of the slide above the ground
svp [43]
Using the information given we will only need the Cosine and Sine equations.  i made a diagram (cant take a picture, in my study hall) labeled the sides of the triangle A, B, and C.  with C as the hypotenuse, A as the Opposite, and B as the adjacent (will not be needed as A is the height). i will be rounding the th nearest thousandth. 
Using Sine (SIN=Opposite/Hypotenuse), we can find A.

SIN(33)=A/4.4

SIN(33)≈.545

.545≈A/4.4

now multiply each side by 4.4 to get rid of the division

(.545*4.4)≈((A/4.4)4.4)

2.396≈A
 

so the answer would be that the slide is about 2.396 M high
