I need help with this problem

Mathematics
1 answer:
m_a_m_a [10]2 years ago
8 0

Answer:

a. 74°

Step-by-step explanation:

Angle BCD and angle ACB are supplementary because they form a straight line. This means they add up to 180. We can write an equation to model the situation:

m<BCD + m<ACB = 180

106 + m<ACB = 180

m<ACB = 74

Since we are given two sides of the triangle are congruent, the triangle is isosceles. The base angles of an isosceles triangle are congruent, so we can say:

m<ACB = m<A

This means m<A is equal to 74°

Choose the numbers that are irrational.
ddd [48]
As the numbers are written, none of them are irrational because they are all terminating decimals:

3.624=\dfrac{3624}{1000}=\dfrac{453}{125}
0.6=\dfrac6{10}=\dfrac35
0.87=\dfrac{87}{100}
-5=-\dfrac51

Perhaps there is some missing notation in your question?

If you could help I would really appreciate it, but if not that’s fine. Thank you.

Answer:

3

Step-by-step explanation:

j(2) means that x equals 2...

the first inequality in the function says that x is greater than or equal to 2

the second inequality states that x is greater than 2(not equal to) and is less than or equal to 5

the third one states that x is greater than 5

x applies to the first inequality since we know that x can be equal to 2

Now, to the number before the if

there is a 3 before the if in the first inequality

This means that if x is greater than or equal to 2 the y or the function would equal 3

therefore, j(2) would equal 3

I hope this helps!!!
