Answer: x = 5
Step-by-step explanation: This is an isosceles triangle, which means two sides are equal in length and two angles are equal in measurement.
Line BA = Line BC
Similarly, Angle A = Angle C
Angle A plus Angle C equals 146°
Also the sum of the interior angles of a triangle is 180°
Therefore, 146 + (6x + 4) = 180
Subtract 146 from both sides of the equation
6x + 4 = 34
Subtract 4 from both sides of the equation
6x = 30
Divide both sides of the equation by 6
x = 5
Answer:
84 cm³
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
__
The base is shown as a right triangle with legs 8 cm and 7 cm. Its area is given by the triangle formula ...
A = 1/2bh
A = 1/2(8 cm)(7 cm) = 28 cm²
Then the volume of the triangular pyramid is ...
V = 1/3(28 cm²)(9 cm) = 84 cm³
