Answer:
A. 27 degrees, 63 degrees, 90 degrees.
Step-by-step explanation:
Let the angle of the triangle be x
<u>Given the following data;</u>
3 : 7 : 10 = 3x : 7x : 10x
We know that the sum of the sides of a triangle is equal to 180 degrees.
3x + 7x + 10x = 180
20x = 180
x = 180/20
x = 9
<u><em>For the first side;</em></u>
3x = 3 × 9 = 27°
<em><u>For the second side;</u></em>
7x = 7 × 9 = 63°
<em><u>For the third side;</u></em>
10x = 10 × 9 = 90°
Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.
-7 is term in the given expression
Answer:
c
Step-by-step explanation:
both cos and sin are negative values(they are in the 3rd quadrant) and tan=sin/cos and a negative/negative=positive
Answer:
6
Step-by-step explanation:
Use your fingers 13-7=6
Ok you need to do y-(-2) over -3-(-9) and you get(y+2)/(-3+9)=1
so y+2=1*6
y+2=6
y=4
