Answer:
(X+4)(x+4)
Step-by-step explanation:
First find two numbers that multiply to 16 but add up to 8. That is 4 times 4. Then find the root of x squared which is x. The insert x + 4 in parenthesis for both sets because they are both positive. The two sets of parenthesis are supposed to be multiplied with the FOIL method to get x^2+8x+16. Hope this helps :)
Triangle Angle-Sum Theorem: The sum of the measures of interior angles is equal to 180°.
Then
m∠1+117°+33°=180°,
m∠1+150°=180°,
m∠1=180°-150°,
m∠1=30°.
Answer: option A
Answer:
that's easy 4/15- 1/15=3/15,9 15/24-2 9/24=7 6/24, 1 5/1+1 1/1= 2 6/1 there
Step-by-step explanation:
Given :
- The measures of the angles of triangle ABC are in the ratio 2:4:9.
To Find :
- The measures of the angles.
Solution :
- Let the angles of the triangle be 2x, 4x and 9x
We know that the sum of the angles of the triangle is 180°
So,
⠀⠀2x + 4x + 9x = 180°
➺ 15x ⠀⠀⠀⠀⠀⠀= 180°
➺ x ⠀⠀⠀⠀⠀⠀⠀= 180°/15
➺ x ⠀⠀⠀⠀⠀⠀⠀= 12°
⠀
So, The measure of the three angles are :
- 2x = 2 × 12° = 24°
- 4x = 4 × 12° = 48°
- 9x = 9 × 12° = 108°
