Answer:
complementary, x=60
Step-by-step explanation:
complementary angles add up to 90 degrees.
90= x + x- 30
2x= 120
x= 60
Answer:
![x = \frac{1}{2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Step-by-step explanation:
We want to solve for x in the equation in
![x + 4 = 5x + 2](https://tex.z-dn.net/?f=x%20%2B%204%20%3D%205x%20%2B%202)
Let us group like terms to obtain:
![4 - 2 = 5x - x](https://tex.z-dn.net/?f=4%20-%202%20%3D%205x%20-%20x)
We now combine the terms to get:
![2 = 4x](https://tex.z-dn.net/?f=2%20%3D%204x)
Divide both sides by 4
![x = \frac{2}{4} = \frac{1}{2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B2%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Answer:
easy peasy lemon squeazy
Step-by-step explanation:
in this circle, BC is the diameter,
hence, BCA is a semicircle,
and we know that, angle subtended by a semicircle at any point inside the semicircle is 90°,
therefore by angle sum property of triangles, we have
in ΔABC
∠A + ∠B + ∠C = 180°
=> 90° + 50° + ∠C = 180°
=> ∠C = 180° - 140°
=> ∠C = 40°
