Answer:

n=5

Step-by-step explanation:

We can first expand the 3(n+3) into 3n + 3*3. The equation now looks like this. 3n+9-9=15. 9-9=0, so now it is just 3n=15. We divide both sides by 3, and get n=5.

Answer:

n = 5

Step-by-step explanation:

3(n + 3) - 9 = 15

Add 9 to each side

3(n + 3) - 9+9 = 15+9

3(n+3) = 24

Divide each side by 3

3/3(n+3) = 24/3

n+3 = 8

Subtract 3 from each side

n+3-3 = 8-3

n = 5

Answer:

Measure of angle s:

Sum all angles of triangle is = 180 degrees

So,

31 + 58 + x = 180

x = 180 - 31 - 58

x  = 91

Measure of angle s: 91 degrees

ST = 17.005

RT = 33.012

Hope this helps you. Do mark me as brainlist.

Fine the value of x in the triangle. Then classify the triangle as acute, right, or obtuse. 83, obtuse 88, acute 87, obtuse 98,
nika2105 [10]

Answer:

x=88, so it is acute.

Step-by-step explanation:

The two known angles are 45 degrees and 47 degrees. We know that in a triangle, the three angles always add up to 180 degrees.

This means that the third angle is 180-(45+47), or 180-92, or 88. So, the third angle is 88 degrees.

Acute triangles are when all the angles are less than 90. Right is when one angle is exactly 90. Obtuse is when one is more than 90. 88, 45, and 47 are all less than 90, so it is an acute triangle.
