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
the answer is 252 or A. not 100000
Hi there
To know if you are going to divide in a word problem, you should look out for key words.
Some examples of key words for division might be per, a, out of, ratio of, or quotient of. Sometimes, the word problem might straight up tell you to divide.
If you have an example word problem, I could try to help you with it.
Good luck!
C is the correct answer.<span />
Hi! Let me help you!
Before I answer your question, I should first introduce you to triangles! There ae three triangles: Isosceles triangle, equilateral triangle, and scalene triangle. If I remember it right, isosceles triangles have at least one line of symmetry; an equilater triangle must have three lines of symmetry; a scalene triangle HAS NO line of symmetry.
Now, to answer your question: the answer is FALSE. Scalene triangles have no line of symmetry.
I hope this helped you!
