Answer:
<em>102°</em>
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
<em>m∠A</em> = (3×38 - 12)° = <em>102°</em>
Answer:
x ≈ 25.1
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° = 
= 
( multiply both sides by x )
x × sin26° = 11 ( divide both sides by sin26° )
x = 
≈ 25.1 ( to 1 dec. place )
Answer:
d)-8
Step-by-step explanation:
- -6s-¹t²
- -6(3)-¹(-2)²
- -6(⅓)(4)
- -8
The difference in Elevation is 280
3y^2 and -3/4y^2
5x and 2/3x
12x^2
