In the figure, the triangle ABC is a right triangle, a is the adjacent leg to the angle B, and b is the opposite side to the same angle.
So, you can use the tangent ratio which relates the angle, the opposite leg and the adjacent leg:
tangent (angle B) = b / a => b = a * tan(B)
=> b = 12 * tan(48°) = 13.33≈ 13
Answer: 13
I realise this is quite late but in case you still wanted the answer, the width is 3m.
If the length is 3m longer than the width, you can write the width as x and the length as x + 3. The perimeter would be both lengths and both widths added together, so you would just write it as:
x + x + x + 3 + x + 3 = 18
4x + 6 = 18
- 6
4x = 12
÷ 4
x = 3
I hope this helps!
Answer:
C AB
Step-by-step explanation:
ADC should measure to 115 degrees if both measurements are equal to 180 degrees.
If not, ADC might be 25 degrees if both measurements are equal to 90 degrees.
Hope this helps.
To solve this problem, you have to determine the value of
the number 3 in both numbers:
6,300 – the number 3 is in the hundreds place so its value
is 300
530 – the number 3 is in the tens place so its value is 30
To answer the question, the value of 3 in 6,300 is 10 times
the value of 3 in 530.
