Answer: x =9
Step-by-step explanation:
These are corresponding angles, meaning they are equal. (the same angle). Set them equal to each other to solve. 13x+ 3 = 12x +12. Subtract 3 from both sides. 13x = 12x + 9. Subtract 12x from both sides. X = 9
Answer:
The volume of a pyramid is 1/3 x Base Area x Height.
Step-by-step explanation:
<span>D-21.4=87.9 \ solve for D
add 21.4 to both sides
</span><span>D - 21.4 +21.4 =87.9 + 21.4
simplify
D = 109.3</span>
The answer is less than 90 but greater than 35. because the other angles look as if they are 105 I would say that the answer is 75
