Answer:

x=21°

Step-by-step explanation:

in the isosceles triangle, if two sides are equal,then the angles opposite those sides are equal.

so, 2x=42° ( exterior angle of a triangle is equal to the sum of the two opposite interior angles)

x=21°

Find the x -intercept and y -intercept of the line. 3x-6y=12<br> find the X and Y intercept
Andreas93 [3]
3x-6y=12 
y=mx+b 
-6y=-3x+12 <- divide by -6 to make y by itself 
y=1/2x-2 
The y-intercept is (0,-2) 
x-intercept: put 0 in for y
0=1/2x-2 
2=1/2x 
x=4 
(4,0) 
Y intercept: (0,-2) 
X-intercept (4,0)

105% as a fraction is 1.05,

Multiply 1.05 to 25

Your final answer should be $26.25 :)

The line passes through the points (-5,0) and (-1,-4)<br> The slope of the line is
kotykmax [81]

Answer:

-1.

Step-by-step explanation:

First, you find the distance from the first x coordinate to the second. This is done by doing -5 - -1 (aka -5 + 1), which equals -4. Then, you find the distance form the first y coordinate to the second. THis is done by doing 0 - -4 (aka 0 + 4), which equals 4. Then, you divide the distance of the y's over the distance of the x's, which gets you the slope, which is -1. Hope this helped!

The area of a rectangle is 1,036 cm and its length is 74 cm.
Nikitich [7]

Answer:

(i) Breadth = 14 cm

(ii) Perimeter = 176 cm

Step-by-step explanation:

Given,

  • Area of a rectangle = 1036 cm²
  • Length = 74 cm

(i) Breadth = ?

We know that, Area of a rectangle = length × breadth.

Then,

1036 = 74 \times Breadth\\1036  \div 74 = Breadth\\\boxed{\bf\:14 \:cm = Breadth }

(ii) Perimeter of a rectangle = 2 (length + breadth)

Then,

Perimeter = 2(74 + 14)\\Perimeter = 2(88)\\\boxed{\bf\: Perimeter = 176 \: cm}

\rule{150pt}{2pt}

Robin randomly selects a number between 1 and 20 what is the probabilty that the number selected is the square of a natural numb
Ket [755]
Squares of Natural numbers from the range of 1 to 20:
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
(whereas 5^2 = 25 which is outside the range).

There are 4 numbers out of 20, so the probability is 4/20*100% = 20%
