Answer:
13.86 to the nearest tenth.
Step-by-step explanation:
A right angled triangle has three sides and it also has three angles. One of the angles is always 90 degrees while the other two angles are complimentary angles. This means that they add up to give 90 degrees.
The longest side is called the hypotenuse.
One of the shorter side is called the opposite.
The other shorter side is called the adjacent.
From the information given,
The length of the hypotenuse = 19cm
The length of the opposite side = 13cm
The length of the adjacent side = xcm
Applying Pythagoras theorem,
Hypothenuse ^2 = adjacent^2 + opposite ^2
19^2 = x^2 + 13^2
x^2 = 361 - 169 = 192
x = √192 = 13.8564
= 13.86 to the nearest tenth.
Answer:y = 3x/4 + 4
Step-by-step explanation:
The equation of a line in the slope-intercept form is represented by
y = mx + c
Where c = y-intercept
Slope, m = change in the value of y on the vertical axis / change in the value of x in the horizontal axis.
change in the value if y is y2 -y1 and change in the value of x is x2 - x1
Where
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
From the graph,
y2 = 4
y1=0
x2=0
x1 = -3
we can determine the slope.
Slope, m = (4-0) / (0- -3)
= 4/3
Let us pick points (0,4) to determine the intercept
Substituting x = 0 , y = 4 and m = 4/3 into the slope-intercept equation,
y = mx + c
4 = 3/4×0 + c
c = 4
Equation of the line in slope-intercept form is
y = 3x/4 + 4
Use pemdas, parenthesis, exponents, multiplication/division, addition/subtraction. thats the best way to explain how to do this.
Answer:
C. 70 in^2
Step-by-step explanation:
What you do is use the formula for finding the area of a trapezoid.
A=a+b/2(h).
a=8
b=12
h=7
A=8+12/2(7)=70 in^2 is your answer.
