We know that the measure of arc AC = 92 degrees, and x and y are both inscribed angles of this arc, which means that they will have 1/2 of its measure.
Therefore, x = 1/2 (92) = 46 degrees and y = 1/2 (92) = 46 degrees
x = 46, y = 46 is your answer, or the first option
X+y+z=62
second number (y) is equal to the first (x) diminished by 4 means
y=x-4
third (z) is 4 times the first (x) means
z=4x
sub 4x for z and x-4 for y
x+x-4+4x=62
add like terms
6x-4=62
add 4 to both sides
6x=66
divide both sides by 6
x=11
sub
y=x-4
y=11-4
y=7
z=4x
z=4(7)
z=28
the numbers are 11,7,28
the numbers are represented by n; n-4; 4n, first choice
Answer:
(a)
Step-by-step explanation:
using the following
The sum of the 3 angles in a triangle = 180°
The sum of the angles on a straight angle = 180°
To find x subtract the sum of the 2 given angles in the triangle from 180
x = 180 - (56 + 38) = 180 - 94 = 86 ( sum of angles in a triangle )
To find z, subtract x from 180
z = 180 - 86 = 94 ( angles on a straight angle )
To find y subtract the sum of the 2 angles from 180
y = 180 - (94 + 19) = 180 - 113 = 67
x = 86, y = 67 and z = 94
