Since the sum of the angles of a triangle is 180 degrees, we simply have to add all the angles and equate it to 180 to solve for x. So:
100 + 12x + 4 + 14x - 2 = 180
26x = 78
x = 3

So, x is equal to 3.

What is the point-slope form of a line that has a slope of 3 and passes through the point (-1, 4)?
Keith_Richards [23]

Answer:

Step-by-step explanation:

hello :

the point-slope formula is :  

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

in this exercice :  x_1 = -1            y_1 = 4             m = 3 

so : y - 4 = 3(x +1)   ...an equation for this line .

Ok guys i need some help
Strike441 [17]
Hello!

The surface area is the area of all of the shapes on the net added up. First we will find the area of the two triangles.

A=0.5bh
A=0.5(3·6)
A=0.5(18)
A=9

Since there are two triangles we double this area, giving us 18.

Now let's find the length of the two side rectangles.

7(4)=28
28+28=56

Now to find the middle rectangle.

6(7)=42

Now we add up all of the area to find the surface area.

42+56+18=116

The surface area is 116 cm².

I hope this helps!

Find the lateral area of a cylinder whose radius is 6 cm and height is 20 cm.
zaharov [31]
The surface area of a cylinder is define by the formula S.A.=2πrh+2<span>πr^2, where the first part of the formula refers to the lateral area, perimeter, or circumference and the second part to the area of the bases, which are circles.

On this exercise it is asked to find the lateral area of a cylinder whose radius is 6 cm, and has a height of 20cm. To find the lateral area of the cylinder you should substitute this values into the formula, S.A.=2</span>πrh, and as can be seen the answers are given in terms of <span>π or pi.

S.A.=2</span><span>πrh
S.A.=2</span><span>π(6cm)(20cm)
S.A.=2</span><span>π(120cm)
S.A.=240</span>π cm^2

The lateral area of the cylinder is 240
<span>π cm^2 or in other words letter B from the given choices.</span>
