yw good luck
i did the three questions then i put some math notes in the bottom right corner
Answer:
45*
Step-by-step explanation:
180-115=65
65=angle 2
180-110=70
70=angle 1
70+65=135
180-135=45
45=angle 7
angle 7 and 6 are vertical angles so angle 6=45
angle 6 and angle 5 are an example of alternate interior angles soo
angle 5=45*
Hope I helped!

The area of the whole room = 14 × 18 = 252
Since they divide it by half, divide the are by 2.
252 ÷ 2 = 126
Answer = 126 ft²

Answer:
D = 35.8 degrees
Step-by-step explanation:
In this question, we are asked to use calculator to estimate the approximate measure of angle D given its tan value.
From the question, what we have is;
tan D = 0.72
Now to calculate the acute angle D, we will divide through by tan
hence,
D = tan^-1 0.72
or more simply tan^-1 can be called arc tan
Thus, D = arc tan 0.72
D = 35.75
D = 35.8 to the nearest tenth of a degree
