A triangle has a base of 3⅖ inches and an area of 5⅒ square inches. Find the height of the triangle. Show your reasoning

N76 [4]

Answer: 3 in.

Step-by-step explanation:

Given

The base of the triangle is $3\frac{2}{5}\ inches$

The area of the triangle is $5\frac{1}{10}\ inches^2$

Solve mixed fraction

Base is

$=3\dfrac{2}{5}\\\\=\dfrac{17}{5}\ in.$

Area is

$=5\dfrac{1}{10}\\\\=\dfrac{51}{10}\ in.^2$

The area of the triangle is given by

$\Rightarrow \text{Area A=}\dfrac{1}{2}\times \text{base}\times \text{height}$

Insert the values to get the height

$\Rightarrow \dfrac{51}{10}=\dfrac{1}{2}\times \dfrac{17}{5}\times \text{height}\\\\\Rightarrow \text{height}=3\ in.$

For an angle θ with the point (15, −8) on its terminating side, what is the value of cosine?

malfutka [58]

Answer:

The value of cosθ is $\frac{15}{17}$

Step-by-step explanation:

It is given that an angle θ with the point (15, −8) on its terminating side.

Here x=adjacent side=15 units and y=opposite side =-8 units,

Using pythagoras theorem,

$\text{hypotenuse}^2=\text{base}^2+\text{opposite side}^2$

$\text{hypotenuse}^2=(15)^2+(-8)^2$

$\text{hypotenuse}^2=225+64=289$

$\text{hypotenuse}^2=17$

Cosine is defined as

$\cos \theta=\frac{base}{hypotenuse}$

$\cos \theta=\frac{15}{17}$

Therefore the value of cosθ is $\frac{15}{17}$ .

What is the gcf of 75 and 90.

choli [55]

75 = 3*5*5

90 = 2*3*3*5

Picking out common factors the GCF = 3*5 = 15 (answer).
