Answer: t=20°
Step-by-step explanation:
1. By definition, the sum of the interior angles is 180 degrees.
2. Keeping the information above on mind, you can write the following expression:

3. Now, you must solve for
as following:

4. Therefore, the value of
is 20°

Answer:
-1 to the nearest whole number.
Step-by-step explanation:
(-0.3) ÷ (-0.2)+(-2.56)
Order of operations - the division is done first:
= 1.5 = (-2.56)
= 1.5 - 2.56
= -1.06.
3% of x = 354

Solution:
The difference of cubes identity is
if a and b are any two real numbers, then difference of their cubes , when taken individually:
→a³ - b³= (a-b)(a² + a b + b²)→→→Option (D) is true option.
I will show you , how this identity is valid.
Taking R H S
(a-b)(a² +b²+ab)
= a (a² +b²+ab)-b(a² +b²+ab)
= a³ + a b² +a²b -b a² -b³ -ab²
Cancelling like terms , we get
= a³ - b³
= L H S
