Answer:
39°
Step-by-step explanation
I’m pretty sure this is 39° because of the interior angle theorem.
.makeo because 4 is how much their is and 3 and 2 are how much they at there for 3 is morn than 2 so makeo
Answer:
57.7 m
Step-by-step explanation:
Since the distance between Isabella, the building and the angle form a right angled triangle with the height of the building = h = 50 m as the opposite side and x = distance between Isabella and the building = adjacent side and Ф = angle of elevation of the top of the building from Isabella = 30°.
So, from trigonometric ratios,
tanФ = h/x
and x = h/tanФ
= 50 m/tan30°
= 50/0.5774
= 86.6 m
Also, the distance between Alice, the building and the angle form a right angled triangle with the height of the building = h = 50 m as the opposite side and x' = distance between Alice and the building = adjacent side and Ф' = angle of elevation of the top of the building from Alice = 60°.
So, from trigonometric ratios,
tanФ' = h/x'
and x' = h/tanФ'
= 50 m/tan60°
= 50/1.7321
= 28.87 m
So, the distance between Isabella and Alice, x" = x - x'
= 86.6 m - 28.87 m
= 57.73 m
≅ 57.7 m
Answer:
The sine = 0.2724 and the cosine = -0.9615 to 4 decimal places.
Step-by-step explanation:
The point (-7,2) is in the second quadrant .
The sine is positive and the cosine is negative,.
The hypotenuse of the triangle in the second quadrant = √((-7)^2 + 2^2)
= √53 ( by Pythagoras), the opposite side = 2 and the adjacent side = -7.
So the sine of the angle is 2 /√53 and the cosine is -7/√53.
or 0.2724 and -0.9615 to 4 decimal places.
