Answer:
3/5
Step-by-step explanation:
sin theta=opposite/hypotenuse
4/5=opposite/hypotenuse
therefore opposite=4 and hypotenuse=5
for adjacent
using pythagoras theorem
a^2+b^2=c^2
opposite^2 + adjacent^2 =hypotenuse^2
4^2 + adjacent^2 =5^2
16 + adjacent^2 =25
adjacent^2 =25-16
adjacent =
adjacent=3
cos theta=adjacent/hypotenuse
=3/5
therefore the value of cos theta is 3/5
Interior angles of a triangle should always add up to 180.
180-154=26
26-13=13
X=13
Answer:
c
Step-by-step explanation:
10 times 8 = 80
80 times 3 = 240
It would be A. R= 50 +10m
If we have a line, and the endpoints are(x₁,y₁) and (x₂,y₂), the midpoint will be:( (x₁+x₂)/2 , (y₁+y₂)/2 );
Data:
Endpoint₁: (2,-3)
Midpoint: (6,6)
Therefore:
(2+x₂)/2=6
2+x₂=12
x₂=12-2
x₂=10
(-3+y₂)/2=6
-3+y₂=12
y₂=12+3
y₂=15
Answer; the other endpoint of a line will be (10,15)
