Answer:
90°
Step-by-step explanation:
we know that
The side TD is perpendicular to the plane formed by the square base ABCD of the cube
therefore
The measure of angle ∠TDB is 90 degrees
The answer is b. y = x over 2
Kahal made an error in step 1 in his calculation.
Step-by-step explanation:
Inequality solved by Kahal;
4x-4>20
Steps used by Kahal
step 1: 4x-4>20
step 2: 4x>16
step 3: x>4
Kahal made mistake in first step where he subtracted 4 from 20. because to eliminate 4 we will add 4 on both sides which will make;
Step 1: 4x-4+4 > 20+4
4x>24
Thus,
Kahal made an error in step 1 in his calculation.

Answer:
-0.2
Step-by-step explanation:
So we would want to isolate x. Start by multiplying both sides by -3. Since we are multiplying negative number, we flip the sign.
So that would be x ≥12. That means x should be greater than or equal to 12.
So now it's easy to answer.
C, D, E would be the answer.
