Answer:
x = 9.9
Step-by-step explanation:
This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.
In this case, multiply. The side measurement of 1 has 7.
1 x 7 = 7
In the same, you must multiply 7 with √2
x = 7 * √2 = 7√2.
√2 = ~1.414
7 x 1.414 = 9.898
Round to the nearest tenth:
9.898 rounded to the nearest tenth = 9.9
x = 9.9

Answer:
Option A is the correct answer.
Explanation:
The given pyramid has 3 lateral triangular side as shown below.
Base of triangle = 12 unit
We need to find perpendicular.
By Pythagoras theorem we have
Perpendicular² = 10²-6²
Perpendicular = 8 unit
So area of 1 lateral triangle = 1/2 x Base x Perpendicular.
= 1/2 x 12 x 8 = 48 unit²
Area of lateral side = 3 x 48 = 144 unit²
Option A is the correct answer.
Answer:
<u>x = - 7</u>
Step-by-step explanation:
Step 1:
2x + 3 = x - 4 Equation
Step 2:
x + 3 = - 4 Subtract x on both sides
Answer:
<u>x = - 7</u> Subtract 3 on both sides
