Answer:
it's
Step-by-step explanation:
(2f+2)(2f-2)
(2f^2-2^2)
Two negatives make a positive
For the first triangle x=70. 180-40 is 140. Divided that by 2 and you’d get 70.
The second triangle x=90. 180-45 is 135. 135-45 (the angle congruent to the other 45 degree angle) is 90.
The third triangle x=65. 180-50 is 130. 130 divided by two is 65.
Check all answers by adding all the angles of the triangle and make sure they equal 180
Answer:
(98+89+88+x)/5 > 92
366+x/ 5 > 92
x/5 + 73.2 > 92
x/5 > 18.8
x > 94
The lowest score that you can make and have a 92 average is a 94. Hope this helps!
