Step-by-step explanation:
2. 12-8+4+9x(40+4)
12-8=4
4+4=8
8+ 9x(40+4)
add 40+4=44
8+9x(44)
396x+8
the is the answer
3. (18-9)×4+8+35-5
add 8+35=43-5=38
(18-9)×4+38
4 times 18 equal 72
-9 times 4 equal -36
72-36+38
the answer is 74❤
hope this helps
A triangle has a total degrees of 180, so you add 55 and 53 to get 108
then you subtract that from 180 to get 72. 72 is your answer
Answer:
83 m (nearest metre)
Step-by-step explanation:
This can be modeled as a <u>right triangle</u>, where the base is 60 m and the height is the height of the building.
<u>Alternate Interior Angles Theorem (Z-angles)</u>
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent.
Using the Alternate Interior Angles theorem, the angle between the ground and the dashed line (angle of elevation) is 54°.
<u>Tan trigonometric ratio</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
Given:
- = 54°
- O = height of building (h)
- A = 60
Substituting the given values into the formula and solving for h:
Answer:
(-3,8)
(-2,5)
(1,2)
(1,7)
(-1,6)

Answer:
0.825
Step-by-step explanation:
In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5
33*2.5 = 66 + 16.5 = 82.5
33/40 = 82.5/100
Now we solve, 82.5/100 = 0.825
