SA=2(LW+LH+WH)
SA=94
L=3
W=4
94=2(3*4+3H+4H)
divide both sides by 2
47=3*4+3H+4H
47=12+7H
minus 12 both sides
35=7H
divide oth sides by 7
5=H
5m
Answer:
15/16
Step-by-step explanation:
To find the value of Sin A can be found using the sine rule. the rule states that the ratio of the length facing an angle in a triangle to the sine of the angle is constant. As such,
a/Sin A = b/Sin B = c/Sin C
Where is a is the side facing angle A, b is the side facing angle B and c is the side facing angle C.
Hence,
8/(3/4) = 10/Sin A
Sin A = 3 * 10 / (8 * 4)
= 30/32
= 15/16
Answer:
Option (C)
Step-by-step explanation:
Formula to get the scale factor of any image from it's preimage,
Scale factor of an image =
From the figure attached,
F' is the image of preimage F after dilation.
Scale factor =
=
=
Therefore, Figure F has been dilated by a scale factor of to form F'.
Option (C). will be the answer.
Step-by-step explanation:
= -4c + 14
hence -4c + 14 is the answer ...
hope it helped !!
