I think they are asking the area of the triangle so we are going with that.

Step-by-step explanation:

Easiest way to do this is find the area of the incomplete square, and then cut that in half for the triangle.

so it is 4 cm wide

and 8 cm tall

length x width = area

8 x 4 = 32

32/2 = 16

THANK YOU !!!

I really don't know how to calculate this question.

(3 tan 45°)(4 sin 60°)-(2 cos 30°)(3 sin 30°)

, which is equal to .

Step-by-step explanation:

An angle of corresponds to an isosceles right triangle: the length of the two legs (adjacent and opposite) would be equal. Accordingly:

.

Let denote the measure of an angle. Double-angle identity for sine:

.

By this identity:

.

( in this instance.)

Hence:

.

. Therefore, .

What is the x-and y-intercept of the graph 4x -5y =40??

x-intercept = 10

y-intercept = -8

Step-by-step explanation:

To identify the y-intercept, we will need to format the equation in the form . We can start by subtracting from both sides of the equation:

Divide both sides of the equation by the coefficient of , which is :

The is representative of the y-intercept in .

Identify in the equation :

Therefore, our y-intercept is -8.

To solve for the x-intercept, replace the in the equation with a zero:

Add to both sides of the equation:

You can go ahead and divide by to get rid of the fraction:

Divide both sides of the equation by the coefficient of , which is :

Therefore, our x-intercept is 10.

A cinema seats 280 people. if 98 people are in the cinema, what percentage of the seats are filled ?

35 percent. Helps if you turn it into a fraction. so 98/280 is the same as .35 convert to percentage and you get 35%

The total number of seats are 280

Out of this 98 seats are filled

Hence it is expressed in fraction as

(part out of whole)

To convert any fraction into percentage, we just need to multiply it with 100

×100

= 35 %

Hence 35% of the cinema is filled
