Answer:

Step-by-step explanation:

So you train of though might lead you to soemthing like this: it must be 90 degrees, since that looks like a 90 degree triangle, and there are 180 degrees in a line. So 90 degrees and 90 degrees make up the 180.

That is exactly what I though.

But, its a bit different from that. We do not know for sure that its a 90 degree traingle. Depending on the angle of the traingle, the outcome of the mystery number is different.

So, to find the angle of the trainge, lets take our 155 degree line.

Now, this is just a simple line. We know the line is 180, and that the other number must add onto 155 to make 180:

180-155=missing angle

25. So we know that the smallest angle of the traingle is 25.

We also know that a traingle has a total of 180 degrees.

We can add the 60 degrees and our new 25 degrees, subtract if from 180, and we will get our last angle of the traingle we need to solve:

60+25

Now subtract it from 180:

180-85

So that last angle of the traingle is 95.

Now, we need to solve the missing angle of the line that will give us the answer.

Again, we know the line has to be 180, so lets subtract 95 from that:

180-95

So we know that the missing angle answer is 85!

I hope this isnt too confusing and helps! :)

Four friends ordered a pizza.Christopher ate 1/5, Emma ate 0.27, and Jamie ate the rest.what percent did Jamie eat?

DENIUS [597]

Percent means parts out of 100

so
1/5=0.20
chris+em+jam=100%=1
0.20+0.27+jam=1
0.47+jam=1
minus 0.47 both sides
jam=0.53
jam=53/100
jam=53%

jamie ate 53%

The cylinder below has r = 10 inches and a volume of 6283 cubic inches to the nearest cubic inch. Find the height of the cylinde

kaheart [24]

V=hpir^2
r=10
v=6283

6283=hpi10^2
6283=100hpi
divide both sides by 100
62.83=hpi
aprox pi=3.141592
divide both sides by pi
19.9994143=h
so about 20 inches

n this triangle, what is the value of x? Enter your answer, rounded to the nearest tenth, in the box. x = cm A right triangle wi

nikklg [1K]

See the attached picture to better understand the problem

we know that
in the right triangle ABC
sin 63°=AB/BC
AB is the opposite side angle 63-----> x cm
BC is the hypotenuse-----> 85 cm
AB=BC*sin 63°-----> AB=85*sin 63-----> AB=75.736 cm
AB=75.8 cm

the answer is
the value of x is 75.8 cm
