Each cm is 5 m so multiply each cm by 5m
Therefore 30cm X 5m/cm = 150 m

2. The following triangle, ∆, has angle measures as shown.

klio [65]

Answer:

x=29. Angle C= 93

Step-by-step explanation:

3(x+2)= 3x+6.

3x+6+52+35= 3x+93.

180-93=87.

87/3= 29. So that means x=29.

for proof you can do 3(29)+93 and you'll get 180.

For angle C; 3(29+2)= 3x31. 31x3= 93.

Angle C= 93 degrees.
