How to do surface area
Mars2501 [29]

Answer:

Step-by-step explanation:

Multiply the length and width, or c and b to find their area. Multiply this measurement by two to account for both sides. Add the three separate measurements together. Because surface area is the total area of all of the faces of an object, the final step is to add all of the individually calculated areas together.

2 trig ratios missing sides and angels
ivanzaharov [21]

Answer:

D

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = \frac{adjacent}{hypotenuse} = \frac{13}{x} ( multiply both sides by x )

x × cos66° = 13 ( divide both sides by cos66° )

x = \frac{13}{cos66} ≈ 32.0 ( to the nearest tenth )

The legs of a right triangle are 12 cm and 16 cm. What is the length of the hypotenuse? 15 cm 17 cm 20 cm 28 cm
GalinKa [24]
Answer: 20 cm

To solve this, use the Pythagorean Theorem, a² + b² = c², where a and b are the legs of the right triangle, and c is the hypotenuse of the right triangle.
**The Pythagorean Theorem only works for right triangles.**

Substitute in the values.
a² +  b² = c²
12² + 16² = c²

Solve for c, the hypotenuse.
12² + 16² = c²               
144 + 256 = c²
400 = c²
c = √400
c = 20

Then you can cross multiply (144 x 100 = 14,400) then divide that answer by 45 (14,400 \ 45 ) The answer you get it 320!!
