Answer:
100
Step-by-step explanation:
0.86 x 100 = 86
Result: 1 2/3 : 4 3/8 = 821 ≅ 0.3809524 ... subtraction fractions: 2/3 - 1/2 • multiplying a fraction by another fraction - multiplication: 7/8 * 3/9 ... multiplying a fraction by a whole number: 6 * 3/4
Step-by-step explanation:
since there are z fishes
the number of angelfish = <u>1</u><u> </u> × z
4
= <u>1</u><u> </u>z
4
X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees.
So your answer is
x=72
Acute Triangle
So,
a parallelogram is forming here
then, opposite angels are going to be equal
so,
y = (x+50)°
now,
as you know that sum of all angles of a quadrulateral equals 360°
so,
2 {(x+50)+(x-30)}=360°
(x+50)+(x-30) = 180°
2x + 20 = 180
2x = 160
x = 80°
therefore,
angle y = (x+50) = 80 +50 = 130°
and x = (x-30) = 80 - 30 = 50°
