Step-by-step explanation:

(2x-11)°+(6x-7)°=180°(being sum of the angle of the triangle is 180°

=2x-11+6x-7=180°

=8x+4=180°

=8x=180-4

=8x=176

=x=176/8

=x=22

A 20 foot ladder leaning against a wall is used to reach a window that is 17 feet above the ground. How far from the wall is the

GarryVolchara [31]

The bottom of the ladder is 10.5 feet away from the wall

Step-by-step explanation:

The given scenario forms a right triangle.

Where

The length of ladder will be the hypotenuse

The wall on which the window is situated will ebt he perpendicular and

The distance between the foot of ladder and the wall will be the base

So,

Hypotenuse = H = 20 foot

Perpendicular = P = 17 feet

Base = B = ?

Using the Pythagoras theorem

$H^2=P^2+B^2\\(20)^2=(17)^2+B^2\\400=289+B^2\\400-289=B^2\\B^2=111\\Taking\ square\ root\ on\ both\ sides\\\sqrt{B^2}=\sqrt{111}\\B=10.53\\Rounding\ off\ to\ the\ nearest\ tenth\\B=10.5$

The bottom of the ladder is 10.5 feet away from the wall

Lisa [10]

Answer:

$D(t)=3 \frac{miles}{hour} +0.05*\frac{miles}{hour*F}(80F-t)$

Step-by-step explanation:

The average speed in function of the temperature:

$S(t)=6 \frac{miles}{hour} +0.1*\frac{miles}{hour*F}(80F-t)$

The distance in function of the average speed:

$D(x)=0.5*x$

x and S are the same

$D(t)=0.5*[6 \frac{miles}{hour} +0.1*\frac{miles}{hour*F}(80F-t)]$

$D(t)=3 \frac{miles}{hour} +0.05*\frac{miles}{hour*F}(80F-t)$

Q # 5 please find the area

ser-zykov [4K]

The Area of a Trapezoid can be calculated as:

Area = 0.5 x Height x Sum of lengths of parallel sides

From the figure, we can see the height, which is the perpendicular distance between two parallel sides is 12.6 inches.

The lengths of parallel sides is 19 and 29.2 inches.

Using the values in the above formula, we get:

Area = 0.5 x 12.6 x (19 + 29.2) = 303.66 square inches

So, the correct answer is option C
