Answer:
x = 5.85641
Step-by-step explanation:
Step 1: Find missing leg of left triangle
sin30° = x/16
16sin30° = x
x = 8
Step 2: Find missing leg of right triangle
8² + b² = 16²
b² = 192
b = 8√3
Step 3: Find <em>x</em> by taking the difference
8√3 - 8 = 5.85641
Answer:
Step-by-step explanation:
Diameter is 7cm
radius is diameter/2 = 7cm/2 = 3.5cm
Answer:
x=30º
∠CAB=60°
∠ACB=80°
Step-by-step explanation:
Because the angles of every triangle add up to 180º, we know that:

x=30º
Plug that in for x on both angles, and you will get
∠CAB=60°
∠ACB=80°
Hi,
Work:
Equation;

Collect like terms and calculate sum of positive numbers.

Move constant +63 to the right side and change its sign.

Subtract numbers.
