Well there’s 180° in one triangle. a right angle is 90°. 2x+3x+90=180. 5x=90 divide by five, x=18°
Answer:
Daughter age = 3 years
Step-by-step explanation:
Let x be the age of the women and y be the age of the daughter.
Given:
After five year the sum of the women and daughter age = 40

Therefore, the daughter age is 3 years.
You could easily change the 2 1/2 to a 2.5 and do 2.5-6=-3.5
Answer:
Step-by-step explanation:
m∠JXM + m∠NXP = 180° - m∠MXN = 90°
120$. 100%
X$. 8.33%
X= 120• 8.33/100
X=9.99 $
