Step-by-step explanation:
Answer:
- 63 ft²
- h = 2A/b; h = 7 ft
Step-by-step explanation:
1. Put the values where the variables are in the formula, then do the arithmetic.
... A = (1/2)bh = (1/2)(18 ft)(7 ft) = 63 ft²
2. Divide by the coefficient of h. Substitute the given values and do the arithmetic.
... A = (1/2)bh
The coefficient of h is b/2, so we divide by that—or multiply by its inverse, 2/b.
... 2A/b = h
Substituting the given numbers, you have ...
... 2(28 ft²)/(8 ft) = h = 7 ft
The height of the triangle is 7 ft.
Answer:
-22
Step-by-step explanation:
(Is that Aleks?)
Plug it in.
(-2)^2 + 9(-2) - 8
= 4 + (-18) - 8
= -14 - 8
= -22
Step-by-step explanation:
Afro Eurasian network of trade basically encompassed all the major routes of trade before the discovery of Americas and thus meant that the tarde of many things was being done in different parts of it and from different parts of it.
The African coasts were rich in minerals and gold so it was traded from there while India and China were rich in silk, cotton, grain along with the very valuable salt which was also a commodity of the eastern and south eastern part of Asia.
The European trade route largely contributed to metals and non metals required for construction as well as other elements.
Check the picture below.
notice the tickmarks, thus TP = PU and TQ = QS, so the PQ segment is then a midsegment of the larger triangle, and thus the angles it makes on the small one, are exactly the same.
