Two vertical angle measure 2x and 80”.How many degrees are there in x.
A) 100
B) 400
C) 1000
D) 1200
Explanation: Vertical angles are formed by two intersecting lines. They are opposite each other and have equal measures. In this case, we have two vertical angles, one measuring 2x and the other measuring 80°.
Since vertical angles are equal, we can set up the following equation:
2x = 80°
To solve for x, we divide both sides of the equation by 2:
x = 80° / 2 x = 40°
Therefore, there are 40 degrees in x.
4ab3c2 is ……………
a) Monomial
b) Binomial
c) Trinomial
d) None of these
Explanation:
Monomial: A polynomial having only one term is called a monomial. For Example, P(x) = 3, P(x) =3x
Binomial: A polynomial having two terms is called a binomial. For Example, P(x) = x + 2, P(x) =3y – 7
Trinomial: A polynomial having three terms is called a trinomial. For Example, x2 + 2x +1, y2 -2y + 4
The number of digits in the square root of 15129
is:
A) 1
B) 2
C) 3
D) 4
Explanation: To determine the number of digits in the square root of 15129, we can calculate the square root of 15129 and count the number of digits in the result.
The square root of 15129 is 123. Since 123 has three digits, the correct answer is: C) 3
