Answer:
8.31m
Step-by-step explanation:
tan 40 = Opp/Adj
tan 40 = x/8
x = 8 tan 40
x = 6.71m
Plus 1.6m = 8.31m
Answer:
See below
Step-by-step explanation:
1 . Missing angle
Sum of interior angles in the triangle = 180°
- 180° - (105° + 29°) = 36°
2. Angle 1
- Angle 1 is exterior angle of the triangle
- Angle 1 = 55° + 78° = 133°
3. Angle 2
- Angle 2 = 180° - (55° = 78°) = 47°
4. The sum of exterior angle and adjacent interior angle equals 180°
If they are equal, then each will measure 180°/2 = 90°
So it is possible with the right triangle
Answer:
y=8x-6
Step-by-step explanation:
Answer: second option.
Step-by-step explanation:
Let be "x" the unknown number.
According to the information provided in the exercise, 10 is the result of the subtraction of "x" and -5.
Based on this, you can write the following equation:

To find the value of "x" you must remember the multiplication of signs:

Then:

Finally, subtracting 5 from both sides of the equation, you get:

Answer:
72
Step-by-step explanation:
If you mutiply 7 x 12 you would get 84 and then minus then how much they just ate to the number of how much there were from mutiplying which would be 84-17= 72
