find the area of a square, width times height
then find the area of the triangle, width times height divided by 2
Answer:
10% of 2,000 is 200. 2000 + 200 = 2200. 10% of 2200 is 220. 2200 + 220 = 2420. Answer is 2420.
Step-by-step explanation:
She starts off with 2000. She earns 10% of 2000 the first year. 10% of 2000 is 200. Then add to get the amount of money she has at the end of that year. 2000 + 200 = 2200. Then the next year she earns 10% of 2200. 10% of 2200 is 220. Add 2200 + 220. 2200 + 220 = 2420.
Answer:
C)38 or B)23, or D)45
Step-by-step explanation:
you can pick but please give me brainliest
C = 71 degrees
b = about 8.70 (8.7)
c = about 15.43
C: All the angles in a triangle add up to 180 degrees. So, to find "C", you add together "A" and "B" (69 and 40) and subtract their total from 180. This will give you C = 71 degrees.
Now we will solve for "b"and "c". When solving for a side angle, you use the following system; a/SinA = b/SinB = c/SinC.
b: Since we can fill in for a/SinA, and the Sin B b/SinB we will use that to solve for "b". Filling in for each know part, you'll get 15/69 = c/71. Next you multiply 15 and 71, then divide by 69 to get b. 15*71 = 1,065. 1,065/69 = 15.4347... which rounded equals 15.43.
c: Using the same steps as "b", we will now find "c". 15/69 = b/40. Multiply 15 and 40, then divide by 69. 15*40 = 600. 600/69 = 8.6956... which rounded equals 8.70 or 8.7.
I hope this helps!
