One acute angle of a right triangle is 12 degrees more than twice the other acute angle. Fine the acute angles of the right tria

Svetlanka [38]

Let one acute angle be X and one be Y
X+Y=90 -------Eq.1
2X+12=Y
2X-Y=-12------Eq.2
solving eq 1&2 we get,
3x=78
∴X=26
substituting value X in equation.1
X+Y=90
Y=90-26
∴Y=64
⇒answer:- X=26°
Y=64°

Could someone help me please?

Answer:

a. 7.2

b. 6

Step-by-step explanation:

Since the side lengths of similar polygons are proportional to each other, therefore:

$\frac{b}{10} = \frac{9}{15} = \frac{a}{12}$

Thus, let's find b using:

$\frac{b}{10} = \frac{9}{15}$

Cross multiply

$b*15 = 10*9$

$15b = 90$

Divide both sides by 15

b = 6

Let's find a using:

$\frac{9}{15} = \frac{a}{12}$

Cross multiply

9*12 = 15*a

108 = 15a

Divide both sides by 15

a = 7.2
