In a right triangle, the measure of one acute angle is 30 less than twice the measure of the other acute angle. Find the measure of each angle.
---
The sum of the 2 acute angles is 90 degrees.
x + y = 90
x = 2y-30
----
Substitute for "x" and solve for "y":
2y-30 +y = 90

3y = 120
y = 40

x = 90-y
x = 90-40
x = 50

Jenna and Heidi together have $60. Jenna has $9 more than twice Heidi’s amount. How much money does each have?
Marina86 [1]

Jenna has $43 and Heidi has $17.

Step-by-step explanation:

Total amount = $60

Let,

Amount of Jenna = x

Amount of Heidi = y

According to given statement;

x+y=60   Eqn 1

x=2y+9   Eqn 2

Putting value of Eqn 2 in Eqn 1;

(2y+9)+y=60\\2y+9+y=60\\3y=60-9\\3y=51

Dividing both sides by 3,

\frac{3y}{3}=\frac{51}{3}\\y=17\\

Putting y=17 in Eqn 2

x=2(17)+9\\x=34+9\\x=43

Jenna has $43 and Heidi has $17.
