Cos (x) = adj/hyp
cos (x) = 13/25
x = cos⁻¹(13/25)
x= 58.7° (nearest tenth)
I didn’t know what totally you wanted so I attached two pictures to try to help :) have a lovely day!
Answer:
1.3
Step-by-step explanation:
3.5 - y
y= 2.2
So substitute the Values and do 3.5 - 2.2 and you get 1.3 as answer
I hope This helped!
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
Step-by-step explanation:
Let,
The longer leg = x
The shorter leg = x-7
Hypotenuse = x+7
Using Pythagoras theorem;
![a^2+b^2=c^2\\(x-7)^2+(x)^2=(x+7)^2\\x^2-14x+49+x^2=x^2+14x+49\\2x^2-14x+49-x^2-14x-49=0\\x^2-28x=0\\x(x-28)=0\\](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2%5C%5C%28x-7%29%5E2%2B%28x%29%5E2%3D%28x%2B7%29%5E2%5C%5Cx%5E2-14x%2B49%2Bx%5E2%3Dx%5E2%2B14x%2B49%5C%5C2x%5E2-14x%2B49-x%5E2-14x-49%3D0%5C%5Cx%5E2-28x%3D0%5C%5Cx%28x-28%29%3D0%5C%5C)
Either,
x= 0
Or,
x-28=0 =>x=28
As length cannot be zero, therefore,
Longer side = 28cm
Shorter side = x-7 = 28-7 = 21cm
Hypotenuse = x+7 = 28+7 = 35cm
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.

Answer:
A linear relationship is a relationship with a constant rate of change represented by a graph that forms a straight line that passes through the origin (0, 0) and is represented by y = kx. The rate of change is either positive, negative, zero, or undefined.
