Answer:
x = 15 degrees
3 angles in triangle are 44, 44 and 92 degrees.
Step-by-step explanation:
When the lines are parallel the internal angles add up to 180 degrees. So:-
8x + 7 + 2x + 23 = 180
10x + 30 = 180
10x = 150
x = 15
In the triangle:-
The angle adjacent to 136 = 180 - 136
= 44 degrees. As 2 sides of the triangle are congruent the other base angle = 44 degrees also.
The third angle = 180 - 2(44) = 92 degrees
Answer:
y = 66
Step-by-step explanation:
11 = y/6
11*6 = y
66 = y
Initial tempuratire is at t=0
T(0)=103e^0+73=103(1)+73=103+73=176 degrees
after 90 mins
T(90)=103e^-0.0182*90+72
T(90)=103e^-1.638+73
T(90)=19.6589+73
T(90)=92.6589 degrees
Answer: 9xy−16.3x−10.2
Step-by-step explanation:
Distribute:
=0.95x+−9+9xy+−18x+(−0.25)(−3x)+(−0.25)(4.8)
=0.95x+−9+9xy+−18x+0.75x+−1.2
Combine Like Terms:
=0.95x+−9+9xy+−18x+0.75x+−1.2
=(9xy)+(0.95x+−18x+0.75x)+(−9+−1.2)
=9xy+−16.3x+−10.2
You must multiply each number for example 8*4*2= 64 so the after math is 64 after all the work the answer is ^4.
