Answer:

15 units

Step-by-step explanation:

From question statement, we observe that

Area of triangle and height of triangle is given.

Area = A = 52.5 square unit    and Height = h = 7 unit.

We have to find the base of triangle.

Base = b =?

The formula to find the Area of triangle is:

Area = 1/2 × base ×height

Hence, base = (2 ×Area ) / height

Putting the given values in above formula, we have

base= (2×52.5) / 7

base = 105 / 7

base = 15 units

15 units is the base of given triangle.

Answer:

base = 15 units

Step-by-step explanation:

We are given area of a triangle = 52.5 sq. units

Height is given as 7 and we have to find the base.

Using formula for area of triangle:

Area of triangle = \frac{base*height}{2}

52.5 = \frac{base*height}{2}

52.5 = \frac{base*7}{2}

52.5 * 2 = base × 7

105 = base × 7

base = 15

Answer:

36 + 16 √3

Explanation!

You would first need to simply the radical by breaking the radicand up into a product of known factors!

So the answer would be 36 + 16 √3

If you want decimal form here you go! :)

Find all angles, 0≤θ<360, that satisfy the equation below, to the nearest 10th of a degree. 4tan^2 θ+tanθ=−4tanθ−1
Serga [27]

Answer:

135 and 315degrees

Step-by-step explanation:

Given the expression

4tan²θ+tanθ=−4tanθ−1

Equate to zero

4tan²θ+tanθ+4tanθ+1 = 0

4tan²θ+5tanθ+1 = 0

Let x = tanθ

4x²+5x+1 = 0

Factorize;

4x²+4x+x+1 = 0

4x(x+1)+1(x+1) = 0

4x+1 = 0 and x+1 = 0

4x = -1 and x = -1

x = -1/4 and -1

Since x = tanθ

-1 =tanθ

θ = arctan(-1)

θ = -45degrees

Since tan is negative in the 2nd and fourth quadrant;

In the second quadrant

θ = 180 - 45 = 135degrees

In the fourth quadrant;

θ = 360 - 45 = 315degrees

Hence the required angles are 135 and 315degrees
