Answer:
Angle 1 and angle 3 are vertical angles.
Step-by-step explanation:
They are diagonal from each other causing it to be vertical angles and equal.
A= 1/2 h ( sum of bases)
SUBSTITUTE
6550= 1/2h (115+85)
6550=1/2h (200)
6550= 100h
65.5= h
height is 65.5 cm
Hope this helps
For this case we can use the law of the sine to solve the problem.
We have then:

From here, we clear the value of x.
We have then:

Rewriting we have:
Answer:
The angle R is given by:
x = 68 degrees
option B
Answer:
negative -14
Step-by-step explanation:
The answer is 2/7 or 0.28571428... You can find this the same way as your other problem by finding the common denominator and multiplying. (Also, if you go on Mathway, you can find solutions to almost any problem really quickly.)
Hope this helps!
