Step-by-step explanation:
3i×2i =6i^2
3i×4 =12i
Answer:
t = - 2
Step-by-step explanation:
- 2(3 + t) - 8 = 5t
- 6 - 2t - 8 = 5t
- 14 - 2t = 5t
- 14 = 7t
- 14/7 = 7t/7
- 2 = t
A triangle is 180 degrees. 180-28=152. so if angle b and c are combined, your answer is 152 degrees.
Answer:
x ≈ 49.5°
Step-by-step explanation:
We use cos∅ to solve this:
cosx = 13/20
x =
x = 49.4584
Answer:
38 cm
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of all its sides.
We have two unknown length, so let's find their lengths first.
x= 10 -6= 4 cm
y= 9 -2= 7cm
Let's add all the lengths together to find the perimeter:
Perimeter
= 9 +10 +2 +6 +7 +4
= 38 cm
