Angle of a triangle measures 115° the other two angles are in the ratio of 4:9 what are the measures of those two angles
nasty-shy [4]

Answer:

20, 45

Step-by-step explanation:

A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles  must add up to 65.

The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9

A ratio partition parts of something. We can add the ratio intergers to find it full length.

4+9=13.

Divide 65/13=5.

Multiply 5x4 and 5x9 serpately.

We get 20 and 45

Math problem help me. I got it wrong I think
lukranit [14]

Answer:

The answer is B

Step-by-step explanation: After solving this equation using y=mx+b

I got y=-4x+7

So they give us the slope which is negative 4

so you would throw in the x coordinate with the slope and multiply to get y=-12+7

then you would use the y coordinate to substitute the Y

-5=-12+7

i add twelve on both sides and end up with the y intercept being 7]

so I add them into the equation and got y=-4x+7

A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for ∏.
bogdanovich [222]

Answer:

66

Step-by-step explanation:

The diameter of the circle is 21. The formula for circumference is pie*radius*2. We don't have the radius but the diameter is just double the radius so just don't multiply by 2. 21 x 22 = 462. 46s divided by 7 is 66. Enjoy your answer :D
