If these triangles are congruent, then side RS is congruent to side TV and that means that y = 4 - x. If y = 4-x, we can sub that into the next equation where side RV = side ST and 1 = 4x - y. If y = 4-x, we sub in accordingly to get 1 =4x - (4 - x). That simplifies to 1 = 4x - 4 + x which is, combining like terms, 5 = 5x. That means that x = 1. If x = 1, and y = 4 - x, then y = 4 - 1 and y = 3. There you go!

Answer:≥2
Step-by-step explanation:
First, we need to translate the problem into algebraic expressions and equations:
[length][is][ten inches more than][twice the width]
⟹[][=][10+][2×]
⟹=10+2
==(10+2)()=22+10
[Area][is at least][28]
[][≥][28]
⟹≥28
Putting these together, we have a quadratic inequality:
22+10≥28
The most straightforward way [I know of] to solve this is to compare to zero, find the roots, and go from there:
22+10−28≥0
⟹2+5−14≥0
Finding the zeros using your favorite method — factoring, quadratic formula, etc. — yields zeros of ={−7,2} .
Since the width of the rectangle can’t be negative, our solution involves =2 . The graph of the quadratic function is concave up (due to the positive leading coefficient), meaning the function is non-negative for ≤−7 or ≥2 — giving us our solution, ≥2 !
Answer:
the measure of angle is m(<a)=40
Step-by-step explanation:
the intirior angles of all triangles add up to 180
with this you can subtract the 90 degree angle and the 50 degree angle from the total of 180 degrees.
180
90
-50
---------
=40 degreese
hoped this helped.
