HELP ASAP!!!!!!
WARRIOR [948]

Answer:

x=26

C = 91

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

A + B+ C = 180

35+ 52+ 3(x+5) = 180

Distribute

35+52+3x+15 = 180

Combine like terms

102 +3x = 180

Subtract 102 from each side

102-102 +3x=180-102

3x= 78

Divide by 3

3x/3 = 78/3

x=26

Now we need to find angle C

c = 3(x+5)

C = 3(26+5)

     3(31)

     93

Which comparison is true?
Setler79 [48]

Answer:

0.3 > 0.09

Step-by-step explanation:

The comparison 0.3 > 0.09 is true.

0.3 = 0.300

0.300 > 0.009

All other options are false. They should have a less than sign instead of a greater than sign.
