I am not exactly sure, but I am almost positive it is a spere
2×5^{2} if you don't understand its 2 times 5 to the second power.
Answer:
x = 11, y = 8
Step-by-step explanation:
ΔABC and ΔFDE are congruent by the postulate SSS
Equate the congruent sides in the 2 triangles
BC = ED, that is
x + 3 = 14 ( subtract 3 from both sides )
x = 11
-------------------------------------
DF = AB, that is
x - y = 3 ← substitute x = 11
11 - y = 3 ( subtract 11 from both sides )
- y = 3 - 11 = - 8 ( multiply both sides by - 1 )
y = 8
The answer will be
-1.8h=-7.2-8.1
h=-15.3/-1.8
h=8.5
