Answer:
Option C is correct.
Step-by-step explanation:
We are given that line and line
are parallel to each other.
We have to find value of x.
Measure of given angle = 120°
Clearly from pic,
Given angle and x are interior angles and on the alternate sides.
So using a result of parallel line which says that Alternate interior angles are equal.
So, x = 120°
Therefore, Option C is correct.
The given expression is
THe given expression is a rational expression, and rational expression should not have 0 in the denominator.
Moreover, the denominator is a square root term, and square root don't have a value for negative number .
Therefore 2x+10 must be greater then 0. That is
Therefore the required domain in set builder form is
{}
Answer:
Therefore,
Step-by-step explanation:
Consider a Δ ABC with
m∠ B= 45°
m∠ C = 90°
AB = c = 15 cm
To Find:
BC = a = y ?
Solution:
Triangle sum property:
In a Triangle sum of the measures of all the angles of a triangle is 180°.
We know in a Triangle Sine Rule Says that,
In Δ ABC,
substituting the given values we get
∴
Similarly for 'x',
Therefore,
