What is the value of x?
Answer:
60
Step-by-step explanation:
180-120= 60
a line is 180 degrees and x is congruent to the angle on the right of 120, meaning if you find the missing angle to that angle(the one next to 120) then you'd get the answer. Knowing the line it 180 and 120 is supplementary to x. x=60.

The length of a rectangle is 3cm more than its width.If the area of the rectangle is 28cm^2,find the width.
Answer: The dimensions of the rectangle are 7 cm × 4 cm
Step-by-step explanation:
let,
Breadth of the rectangle (l) = x
Length of the rectangle (b) = x + 3
Area of the rectangle = 28 cm²
Area of the rectangle = l × b
⇒ (x) × (x + 3) = 28
⇒ x² + 3 x = 28
⇒ x² - 3 x - 28 = 0
⇒ x² - 7 x + 4 x - 28 = 0
⇒ (x - 7) + 4(x - 7) = 0
⇒ (x - 7)(x + 4) = 0
⇒ x = 4
Breadth = 4 cm
Length -
⇒ 4 + 3
⇒ 7 cm
Your television remote control has buttons for digits 0-9. If your press two buttons, how many numbers are possible if
a) the same button may be pressed twice
b) the same button may not be pressed twice
(A) I got 10(10)=100 points in remote space.
(B) I also got 10(9)=90 points in remote space
Answer:
a) 100
b) 90
Step-by-step explanation:
For the first question, the first button you press will have 10 possibilities, from 0-9. For the second button, you will still have 10 possibilities since the same button may be pressed twice. Therefore, you get 10*10=100.
For the second one, the same button may not be pressed twice. For the first button press, you have 10 possibilities, but for the second button, you have 1 less possibility since you aren't allowed to push the button you pressed before. So there will be 9 possibilities. 10*9=90.
In triangle ABC, the measure of angle ABC is 51°
and ACB is a right angle. What is the measure of
angle BAC in degrees?
Answer:
39 degrees
Step-by-step explanation:
The sum of angle in the triangle ABC is a80 degrees
m<ACB + <BAC + <ABC =1 80
90 + <BAC + 51 = 180
141 + m<BAC = 180
m<BAC = 180-141
m<BAC = 39 degrees
Hence the measure of m<BAC is 39 degrees
