- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
3x + 2x + 60° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 5x + 60 = 180
- Isolate <em>x </em>term: 5x = 120
- Isolate <em>x</em>: x = 24
We set up a proportion: ?/42,000= 3/5
Cross multiply:
5*?= 3*42,000
⇒ ?= 3*42,000/5= 25,200
3/5 of 42,000 is 25,200~
Answer:
x = 109°
Step-by-step explanation:
x° is 37° + 72°, due to exterior angle property.
so x° = 109°
Gradient = 5
