10.11 2= r2
r = 10
Answer:
1.5 + 1x
Step-by-step explanation:
8.25 - .25x = 9.75 - .75x
First, add .25 to each side.
8.25 = 9.75 + 1x
Next, subtract 8.25 from 9.75
1.5 + 1x (simplified)
Answer:
Step 2
Step-by-step explanation:
She multiplied by 7 and 25 by 2 instead of 7x7 and 25x25
Answer:
2nd option
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle
sin82° = = = ( multiply both sides by )
× sin82° = KL , then
KL ≈ 3.28 ( to the nearest hundredth )
cos82° = = = ( multiply both sides by )
× cos82° = ML , then
ML ≈ 0.46 ( to the nearest hundredth )
------------------------------------------------------------
The sum of the 3 angles in a triangle = 180° , so
∠ K = 180° - (90 + 82)° = 180° - 172° = 8°
Answer: 13
Step-by-step explanation: 15 x 10 = 150
15x3= 45
150 + 45 = 195
