Answer:
Step-by-step explanation:
A + G + M = 740
A = G - 20
A = M - 120
Therefore,
G = A + 20
M = A + 120
Plug it in...
A + (A + 20) + (A + 120) = 740
Combine like terms
3A + 140 = 740
- 140 -140
3A = 600
/3 /3
A = 200
Double check
A = 200, G = 220, M = 320
200 + 220 + 320 = 740
Step-by-step explanation:
2( l + w ) = perimeter of triangle
P = 2( 10+8 )
p= 2(18)
p= 36cm
Circle = pie (r) + d. recall d = 2r
P= 3.142 (4) + 8
P= 20.57~
so therefore= , 36 + 2(20.57)= 77.14cm ~ to the nearest tenths
The height of the triangle if the base is 8 is 3.96 units
Given the following parameters
Base of a triangle = 8 units
Let the hypotenuse be "c"
Let the height be "h"
If the length of the hypotenuse of a right triangle is one unit more than twice the height, then;
c = 2h + 1
According to the Pythagoras theorem:
c² = b² + h²
(2h + 1)² = 8² + h²
Expand
4h²+4h+1 = 64 + h²
4h²-h² + 4h + 1 - 64 = 0
3h² + 4h - 63 = 0
Factorize the result
On factorizing, the value of the height is 2
h = 
h = 11.89/3
h = 3.96 units
Hence the height of the triangle if the base is 8 is 3.96 units
