Answer:
7*450*.5%
Step-by-step explanation:
Answer:
x=50
Step-by-step explanation:
A= 30+2x
B= x
Supplementary angles are angles that always add up to 180 degrees.
therefore, A + B=180 degrees
30 + 2x + x = 180: Now we solve
<em>30 + 3x =180 </em>
<em>subtract 30 from both sides</em>
3x=150
<em>divide by 3</em>
3x/3 = 150/3
x= 50
Answer:
Step-by-step explanation:
Scale= length on drawing / actual length
Let the actual length b x
3:10=2/5/x
3/10=2/5x
Cross multiply
15x=20
x=4/3
The actual length is 4/3
