Answer:
m∠RMS = 20°
Step-by-step explanation:
Find ∠RMS and look at the two values it crosses.
∠RMS crosses through 180 and 160.
Find the difference between the two values to get the measure:
180 - 160 = 20°
So, m∠RMS = 20°
(Its also an acute angle.)
Answer:
1/ x = 22.5°
2/ x = 60°
Step-by-step explanation:
1/ We have: 3x + 2x + 3x = 180°
=> 8x = 180° => x = 22.5°
2/ We have: x + x + x = 3x = 180°
=> x = 60°
Answer:
S^2 = r^2 + t^2
Step-by-step explanation:
Also you can write it as:
S=sqrt( r^2 +t^2)
