Angle a = 39°
Angle c = 123°
The measure of angle b.
∠ b = 18°
We know that,
➪ ∠ a + ∠ b + ∠ c = 180°
➪ 39° + ∠ b + 123° = 180°
➪ ∠ b + 162° = 180°
➪ ∠ b = 180° - 162°
➪ ∠ b = 18°
Therefore, the measure of ∠ b is 18°.
∠ a + ∠ b + ∠ c = 180°
✒ 39° + 18° + 123° = 180°
✒ 180° = 180°
✒ L. H. S. = R. H. S.
Answer: 9 and 10
Step-by-step explanation:
To understand this question we need to first understand how to solve square root equations! The easiest way to learn how to solve square root problems is by finding the reverse of the problem.
For example, if you tried to find the square root of 25, you would reverse the problem to do 5^2 = 5 x 5 = 25.
So if we were to implement this problem, we would look at these two whole numbers.
9^2 = 9 x 9 = 81
10^2 = 10 x 10 = 100
Thus meaning that the only two numbers that the square root of 97 lies between can be 9 and 10!
It's important to rely on your knowledge of multiplication to develop a strong base for square roots.
Answer:28.28 cm
Explanation:
a² + b² = c²
20² + 20² = c²
c² = 400 + 400
c² = 800
c = √800
c = 28.28 cm
Answer: The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers.
Explanation:
We can convert a point slope equation into standard form by moving the variables to the left side of the equation.
