Answer:
47.0
Step-by-step explanation:
In this right angle triangle, we are faced with a challenge of two sides. The opposite side and the adjacent side, hence the tangent is used.
Where it is the opposite side and hypothenus side, the sine is used and when it is the hypothenus side and adjacent side, the cosine is used.
Hence, we have tan62°=x/25
We cross multiply, to have
25(tan 62°)= x
x = 47.01816
In rounding up numbers, number 1 to 4 will be rounded up to zero, while numbers 5 to 9 will be rounded up to 1.
Rounding up 47.01816 to the nearest tenth. The tenth value is the figure is 0, before it we have 1, which is to hundredth. 1 will be rounded up to zero.
So we have 47.0
Answer:
5
Step-by-step explanation:
Always multiply the base by the height that is straight, (It is more accurate).
2x5=10 and 10/2=5.
The well known formula for the area of a triangle is BxH divided by 2.
Answer:
x = 4, -10
Step-by-step explanation:
Find the zeros of the equations.
Solve the equation:
x^2 + 6x = 40
Subtract -40 from both sides.
x^2 + 6x - 40 = 0
Factor the equation.
(x - 4)(x + 10)
Solve for x with the given information by equaling it to 0.
x - 4 = 0
Add 4 to both sides
x = 4
x + 10 = 0
Subtract 10 from both sides
x = -10
This means that our x values are:
x = 4, -10
Answer:
The value of x would be 104 degrees.
