Answer:

144

Step-by-step explanation:

Ok. I love problems like this.

You just have to find the surface are of each part and add it up!

To find the surface area of a rectangle, you multiple the base and the height. To find the surface area of a triangle, you multiple the base and height, and divide by 2 (because its half of a rectangle).

Left rectangle: 3*ll=33

Middle rectangle: 4*ll=44

Right rectangle: 5*ll=55

Top triangle: 3*4=12

12/2=6

Bottom triangle: 3*4=12

12/2=6

ADD THEM ALL!!! 33+44+55+6+6=144

(Also can I please please please have brainliest? I need it to level up!)

Using the slope formula, find the slope of the line through the given points. (1,6) and (3,4)

svlad2 [7]

To find slope you do y2-y1 over x2-x1. So 4-6 is -2. And 3-1 is 2. So -2/2 is -1. The slope is -1.

(Right angle) Trigonometry please help!

kozerog [31]

Answer:

A = 41.4°

Step-by-step explanation:

Reference angle = A

Length of Adjacent side = 6

Length of Hypotenuse = 8

Apply the trigonometric function, CAH.

Cos A = Adj/Hyp

Substitute

$Cos(A) = \frac{6}{8}$

$A = Cos^{-1}(\frac{6}{8})$

A = 41.4° (approximated to the nearest tenth)

Find cos0 where 0 is the angle shown. Give an exact value, not a decimal approximation.

bogdanovich [222]

Answer:

cos(∅) = 3/5

Step-by-step explanation:

cos(∅) = adjacent/hypotenuse

We don't know what the hypotenuse is so we gotta use Pythagorean theorem to find it.

a² + b² = c²

4² + 3² = c²

√(4² + 3²) = c

c = 5 , this is our hypotenus

cos(∅) = adjacent/hypotenuse

cos(∅) = 3/5
