Question

18. Find the measures of the angles of a triangle if one angle of the triangle is 80° and the other two angles are in
the ratio 3:7
​

Answer 1

the measure of the angle of a triangle is 80 degree and the ratio of the triangle is 3 ratio 7 then we will add a t ratio 7 that means 80 - 3 - 7 the answer will in a small amount that will be the other two angles in r

Answer 2

Answer:

$\huge\fbox{ෆ╹Answer ╹ෆ}$

Step-by-step explanation:

Given:-

• One angle of the traingle is = 80°
• The other two are in the ratio of = 3:7

To Find:-

• The measures of the angles of a traingle

Solution:-

$let \: the \: ratio \: be \: x$

$\huge\fbox{ෆSum of the angle is 180 in a traingleෆ}$

$= > 3x + 7x + 80 = 180$

$= > 3x + 7x = 180 - 80$

$= > 10x = 100$

$= > x = \frac{100}{10}$

$= > x = 10$
