Answer:
30.2
Step-by-step explanation:
cos(58) = 16/BC
BC = 16/cos(58) = 30.2
it looks like its answers two, four, and five.
tell me how you did !
Hi there!
Amit's estimate would be a close estimate!
If you add the fractions together and put it in decimal form you get 4.96 which is very close to Amit's estimate of 5.
Answer:
47 degrees
Step-by-step explanation:
The interior angles of a triangle always equal 180 degrees, so add the other angles together and subtract that from 180
31+102= 133
180-133=47
Answer:
15
Step-by-step explanation:
since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as
13+x+4x+2=90
add the x variables together and the constants separately
15+5x=90
then subtract 15 from both sides.
15+5x=90
-15 -15
5x=75
then divide 5 from both sides.
75/5= 15
so x is 15 :).
