Answer:
Step-by-step explanation:
1x117 = 117
3x39 = 117
9x13 = 117
Answer:
65 degrees.
Step-by-step explanation:
It's hard to explain, but I'll try:
The outside of the first two angles is 105 and 140. Half a whole angle is 180. So, you do
180-140=40. The inside is 40.
And then 180-105=75.
Then you add the two and subtract them from 180:
40+75= 115
180-115=65
Voila!
cos (90° - x) should be the answer
Answer:
cuz im Not very smarttt
Step-by-step explanation:
at all
As i was taught you would use the Pythagorean Theorem, A^2+B^2=c^2 or (AxA)+(BxB)=(CxC)
so if the ladder is 20ft tall the hypotenuse would be 20ft. Now if the ladder is place 5ft from the way the shortest side adjacent to the 90 degree angle would be 5ft
therefore,
20^2=b^2+5^2
400= B^2+25
(400-25)=B^2+(25-25)
375=b^2
The ladder will reach 19.36ft
