Step-by-step explanation:
Answer:
20 square units
Step-by-step explanation:
The figure shows a triangle whose;
- Base AC is 8 units
- Height is 5 units
We are supposed to get its area;
Area of a triangle is given by the formula;
Area = 0.5×b×h
Thus;
Area = 0.5 × 8 units × 5 units
= 20 square units
Hence, the area of the figure is 20 square units
5+4=9 9-2=7
7x(-2)= (-14)
your answer is -14
Answer:
Option C
Step-by-step explanation:
By the property of a rectangle,
"All interior angles of a rectangle measure 90°"
Therefore, m∠ABC = 90°
By applying cosine rule in the right triangle ABC,
cos(∠CAB) = ![\frac{\text{Adjacent side}}{\text{Hypotenuse}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BAdjacent%20side%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D)
cos(25°) = ![\frac{AB}{AC}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BAC%7D)
AC = ![\frac{AB}{\text{cos}(25)}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7B%5Ctext%7Bcos%7D%2825%29%7D)
AC = ![\frac{18}{\text{cos}(25)}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B%5Ctext%7Bcos%7D%2825%29%7D)
AC = 19.86
Therefore, Option C will be the answer.
