Answer:
x = 80
Step-by-step explanation:
We know the sum of the angles of a triangle is 180
x+y+z = 180
Since this is an isosceles triangle y=x
x +x + z = 180
We also know that x = 4z
Writing this in terms of x since we want to find angle x
z = 1/4x
x+x+1/4x = 180
Combine like terms
2x +1/4x = 180
Multiply each side by 4 to get rid of fractions
4(2x +1/4x) = 180*4
8x +x =720
9x = 720
Divide by 9
9x/9 = 720/9
x = 80
Answer:
Step-by-step explanation:
Triangle ABC is a right angle triangle which is made up of 2 right angle triangles.
To determine y, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side². Therefore
136² = y² + 120²
18496 = y² + 14400
y² = 18496 - 14400 = 4096
y = √4096 = 64
To determine z,
255² = z² + 120²
65025 = z² + 14400
z² = 65025 - 14400 = 50625
z = √50625 = 225
K= 35/9
Multiply5/3 on both sides
D is the answer. Hope this helps!
