Answer:
45
Step-by-step explanation:
Substitute 5 for both y values
4 x (5) + (5)^2
Answer:
∠B
7(13)-1=90˚
Step-by-step explanation:
Are you saying ∠ABC or ABC as sides?
1. ∠ABC
(7x-1)+(4x+1)+(3x-2)=180˚
14x-2=180˚
14x=182
x=182/14
x=13˚
2. plug in
∠A
4(13)+1=53˚
∠B
7(13)-1=90˚
∠C
3(13)-2=37˚
Answer:
ASA
Step-by-step explanation:
The triangles are already given 1 congruent corresponding angle and 1 congruent corresponding side. However, there are vertical angles at the point where the triangles intersect, meaning that they are congruent.
So now you have 2 congruent corresponding angles. But they're in the order of Angle-Side-Angle (ASA).

you should draw it in your graph sis
give me some points i have question two
Step-by-step explanation:
Solution: For finding QR we need to apply Pythagoras Theorem
What is Pythagoras Theorem ?
ans : Pythagoras Theorem is the sum of square of two sides which is equal to the third side or the hypotenuse. This formula is valid oy incase of Right-Angled Traingle because one of three angles here is 90°
According to this law let's apply it in the diagram shown here.
- (Hypotenuse)² = (Adjacent)² + (Opposite)²
- (5x - 2)² = (QR)² + (3x - 1)²
- (QR)² = (5x - 2)² - (3x - 1)²
After factorising both of them we get
- (QR)² = 25x² - 20x + 4 - (9x² - 6x + 1)
- (QR)² = 25x² - 20x + 4 - 9x² + 6x - 1
So, QR is √(16x² - 14x + 3)
