Answer:
38°
Step-by-step explanation:
The measure of required angle can be obtained by using cosine law.
From the given triangle we find that:
a = 5, b = 3, c = 7,
Since,
cos (A) = (b^2 +c^2 - a^2) /2bc
Therefore,
cos (A) = (3^2 + 7^2 - 5^2) /(2*3*7)
cos (A) = (9 + 49 - 25) /(42)
cos (A) = (33) /(42)
cos (A) = 0.785714286
A = arccos(0.785714286)
A = 38.213210675°
A = 38°
Answer:
Step-by-step explanation:
start by gathering all the x together.
6x-3x-2x=1x
what you have left is 1x+4=?x+?
Answer:
Total bill = $67.52
Step-by-step explanation:
Ted + 3 = 4
$16.88 × 4 = $67.52
hopefully this helped you :3
The general form for this is y^2 = 4ax where a = focus
the directrix is same distabce behind the vertex as focus is in font so focus a = 4
so we have y^2 = 16 x
or
x = (1/16) y^2
Its C
