Angle BAC
cosφ⁻¹ = (10² + 17² - 11²)/(2*10*17) = 37.9 ≈ 38°
Angle ACB
cosφ⁻¹ = (10² + 11² - 17²)/(2*10*11) = 108.0°
Angle ABC
cosφ⁻¹ = (11² + 17² - 10²)/(2*11*17) = 34.0°
See you !
Answer:
yes, it is.
Step-by-step explanation:
6/9 = 24/36
8/12 = 24/36
Answer:
y = - x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line
m = = -
Note the line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = - x - 3 ← equation of line
Answer:
18
Step-by-step explanation:
1/2 of base times height is AREA OF A TRIANGLE
1/2(6*30)=18
Step-by-step explanation:
use trigonometry
sin33 =c/17
c = sin33 × 17
use calculator for sin33 becauze I dont know the value sorry for that
it will be around 0.5
