We are given the angle measure, measure of hypotenuse and we are to find the base(Adjacent) side of the angle.

Cosine relates all these three as:

$cos(x)= \frac{Base}{Hypotenuse} \\ \\ 
cos(20)= \frac{Base}{2} \\ \\ 
Base=2 *(cos20) \\ \\ 
Base=1.88$

Rounded to nearest hundredth, the measure of side adjacent to the angle is 1.88

Why are 4/10 and 4/100 not equal?

Mrrafil [7]

The same reason 4 dimes and 4 pennies aren't equal.

To put it into decimal terms, 4/10 is 0.40 (or forty cents), whereas 4/100 is 0.04 (or four cents)

What is the slope of each side of the triangle? the sides are A(-2,4) B(-1,1) C(2,3)

Rashid [163]

Answer:

The slopes of three sides of triangle are as follows:

AB = -3

BC = 2/3

AC = -1/4

Step-by-step explanation:

The slope is denoted by m and is calculated using the formula

$m = \frac{y_2-y_1}{x_2-x_1}$

The given vertices are:

A(-2,4) B(-1,1) C(2,3)

The sides will be:

AB, BC, AC

Let m1 be the slope of AB

Let m2 be the slope of BC

Let m3 be the slope of AC

Now

$Slope\ of\ AB = m_1 = \frac{1-4}{-1+2} = \frac{-3}{1} = -3\\Slope\ of\ BC = m_2 = \frac{3-1}{2+1} = \frac{2}{3}\\Slope\ of\ AC = m_2 = \frac{3-4}{2+2} = \frac{-1}{4} = -\frac{1}{4}$

Hence,

The slopes of three sides of triangle are as follows:

AB = -3

BC = 2/3

AC = -1/4

Estimate then find the sum 63,824+29,452

ASHA 777 [7]

90,000 becuase 63,824 is rounded down to 60,000 and 29,452 is rounded up to 30,000. 60,000+30,000 is 90,000
