Answer:

Step-by-step explanation:

1). In ΔABC,

For angle A as a reference angle,

Opposite side of ∠A → BC

Adjacent side of ∠A → AC

Hypotenuse → AB

2). By using tangent ratio in ΔYWZ,

tan(72°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(72°) = $\frac{12}{x}$

x = $\frac{12}{\text{tan}(72)}$

x = 3.899

x ≈ 3.9

3). By using sine rule in ΔKNM,

tan(x°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

tan(x) = $\frac{20}{58}$

x = $\text{tan}^{-1}(\frac{20}{58} )$

x = 19.03

x ≈ 19.0°

4). By applying cosine ratio in ΔJKF,

tan(70°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(70) = $\frac{60}{x}$

x = $\frac{60}{\text{tan}(70)}$

x = 21.838

x ≈ 21.8

$y^2\sqrt[8]{8}$

Step-by-step explanation:

$\sqrt[8]{8*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y*y}$

Since there are eight y's in two groups we can take them out which turns into

$y^2\sqrt[8]{8}$

marta [7]

9) yes, he is correct.

50% as a decimal would be 0.50
7% as a decimal would be 0.07

10)Buy and Bye has a greater discount because 30% as a decimal is 0.30 and 1/4 as a decimal is 0.25.

0.30 is bigger than 0.25 so it is a bigger discount

What is the volume of a pyramid 4 cm,4 cm by 12 cm

Alenkinab [10]

Answer:

The volume of pyramid with dimensions 4cm , 4cm by 12cm is $\bold{64 \mathrm{cm}^{3}}$

Solution:

Volume of a pyramid can be found out by using the below formula,

$\bold{v = \frac{1}{3} l w h}$

where,

v is the volume of pyramid

l is the length of pyramid

w is the width of pyramid

h is the height of pyramid

from question, given that l = 4 ; w = 4; h = 12

hence the volume of pyramid for the given dimensions is

$v = \frac{1}{3} \times 4 \times 4 \times 12$

$= 4 \times 4 \times 4$

$= 64 \mathrm{cm}^{3}$

So the volume of pyramid is $\bold{64 \mathrm{cm}^{3}}$
