A triangle has an angle that measures 95°. The other two angles are in a ratio of 3:14. What are the measures of those two angle
Marta_Voda [28]

Answer: 15° and 70°

Step-by-step explanation:

The sum of angles of a triangle is 180.

One of the angle is given to be 95°, this means that the sum of the remaining two angles will be ;

180 - 95 =  85°

The ratio of the two sides is given to be 3 : 14

Calculating the angles of each ,the angle with the ratio 3 will be

3/17 x 85 = 15°

The angle with the ratio 14 will be

14/17 x 85 = 70°

Therefore : the measures of the two angles are : 15° and 70°

Write an equation of the line passing through the points (4,15) and (-1,- 15).
Art [367]

Answer:

y= 6x-9

Step-by-step explanation:

1. First find the gradient between the two points. Gradient =6

2. Using the formula y= mx+c substitute the gradient into the equation. You'll get something like this: y= 6x+c

3. Substitute the point (4,15) into the equation. You'll get something like this: 15= 6(4) +c.

4. Calculate the value of c. You'll get - 9 as an answer to that.

5. Substitute the value of c into the original equation. Your final answer will be y= 6x-9
