If angle A=(5x+45) and angle A is a straight angle, find the value of x

Mathematics
1 answer:
anastassius [24]3 years ago
5 0

Answer:

x = 27

Step-by-step explanation:

A = 180°

180 = (5x+45)

subtract 45 from each side:

5x = 135

divide both sides by 5:

x = 27

Which exponential function is represented by the values in the table?
svlad2 [7]

Here we use the equation

y = a(b)^x

Taking points (0,4), (1,2)

Substituting the point (0,4) , we will get

4 = a(b)^0
\\
4 = a(1)  \\
a =4

Substituting (1,2) we will get

2 = 4 (b)^1
\\
2/4 = b
\\
b = 1/2

So we have

a = 4, b = 1/2

Therefore , required equation is

y = 4(1/2)^x

These two triangles are similar what is the measure of angle M?
sashaice [31]

Answer:

30

Step-by-step explanation:

We can ignore the fact they are similar altogether. It's known that all 3 angles of a triangle add up to 180, so:

180=102+48+m

180=150+m

30=m
