Solve 3/2 x 90 and (90+45) and (2b-90) B = 90

Mathematics
1 answer:
olga nikolaevna [1]2 years ago
7 0

Answer:

135°, 135°, 90°

Step-by-step explanation:

(3/2)90 = 270/2 = 135

OR 3/2 is just 1.5

1.5•90= 135°

Next: 90+45 = 135°

Finally: 2B -90

= 2•90 - 90

= 180 - 90

=90°

These are the angles you need for your other question. Hang in there!

Can you help me? <br><br> 4+3(x+5)=5x-7
PSYCHO15rus [73]

Answer:

13

Step-by-step explanation:

4 + 3(x + 5)=5 x - 7

3x + 19=5x - 7

3x + 19 - 19=5x - 7 - 19

3x =5x - 26

3x - 5x=5x - 26 - 5x

-2= -26

-2x/-2 = -26/-2

x= 13

It might be wrong. I may have made a mistake with typing sorry.

Hope this helps a bit.

Describe what the graph of the sounds at a rock concert look like.
Romashka-Z-Leto [24]

The graph would be similar to a Sin or Cos graph with a vertical shift. As the music gets louder the graph will go up and as the music and crowd become quieter, the graph will go down. Going up and down until the end of the concert where it will be 0.


Also side note, are you by chance in Trig 01 Summer course? If so, I am in the same class haha.
