ANSWER FAST ILL GIVE BRAINLIEST!!

Dominik [7]

Given:

A square base pyramid whose base length is 10 in. and height of triangular surface is 4 in.

To find:

The surface area of the pyramid to the nearest whole number.

Solution:

A square base pyramid contains square base with edge 10 in. and 4 congruent triangles with base 10 in. and height 4 in.

Area of a square is

$A_1=(edge)^2$

$A_1=(10)^2$

$A_1=100$

So, area of square base is 100 sq. in.

Area of a triangle is

$A_2=\dfrac{1}{2}\times base\times height$

$A_2=\dfrac{1}{2}\times 10\times 4$

$A_2=20$

So, area of each triangular surface is 20 sq. in.

Now, the total surface area of the pyramid is

Total area = Area of square base + Area of 4 congruent triangles.

$A=A_1+4\times A_2$

$A=100+4\times 20$

$A=100+80$

$A=180$

Therefore, the area of the pyramid is 180 sq. in.

Answer:

(a) = 60

(b) = 70

Step-by-step explanation:

(a) Sum of all the angles of a triangle is 180

This is an equilateral Triangle

which means all the sides are equal since all the sides are equal that means all the angles are equal

$x + x + x = 180 \\ 3x = 180 \\ x = \frac{180}{3} \\ x = 60$

(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal

$40 + x + x = 180 \\ 40 + 2x = 180 \\ 2x = 180 - 40 \\ 2x = 140 \\ x = 70$

A jet is coming in for a landing. It's currently 25,000 feet in

Mariana [72]

The angle of depression is 29.0521°. So it is a safe landing.

Step-by-step explanation:

Step 1:

The plane is flying at a height of 25,000 feet and 45,000 feet away from the landing strip. Assume it lands with an angle of depression of x°.

So a right-angled triangle can be formed using these measurements. The triangle's opposite side measures 25,000 feet while the adjacent side measures 45,000 feet. The angle of the triangle is x°.

To determine the value of x, we calculate the tan of the given triangle.

$tanx = \frac{opposite side}{adjacent side}.$

Step 2:

The length of the opposite side = 25,000 feet.

The length of the adjacent side = 45,000 feet.

$tan x = \frac{25,000}{45,000} = 0.5555.$

So x = 29.0521°. Since x < 30°, it is a safe landing.
