200 - (2x) = 42
200 - 42 = 2x
158/2 = 2x/2
x = 79
he is 79 years old
hope this helps
a wise 'old' man
Answer:
The answer is A
Step-by-step explanation:
The point is at one then it goes up to 600 so yea
Problem 4
a)
MR = AG is a true statement because MARG is an isosceles trapezoid. The diagonals of any isosceles trapezoid are always the same length.
-------------------------
b)
MA = GR is false. Parallel sides in a trapezoid are never congruent (otherwise you'll have a parallelogram).
-------------------------
c)
MR and AG do NOT bisect each other. The diagonals bisect each other only if you had a parallelogram.
=================================================
Problem 5
a)
LC = AJ (nonparallel sides of isosceles trapezoid are always the same length)
x^2 = 25
x = sqrt(25)
<h3>x = 5</h3>
-------------------------
b)
LU = 25
UC = 25 because point U cuts LC in half
LC = LU+UC = 25+25 = 50
AJ = LC = 50 (nonparallel sides of isosceles trapezoid are always the same length)
AS = (1/2)*AJ
AS = (1/2)*50
<h3>AS = 25</h3>
-------------------------
c)
angle LCA = 71
angle CAJ = 71 (base angles of isosceles trapezoid are always congruent)
(angleAJL)+(angleCAJ) = 180
(angleAJL)+(71) = 180
angle AJL = 180-71
<h3>angle AJL = 109 </h3>
The value of x in the angle ABC is 25.
<h3>How to find the angles in circle?</h3>
The measure of an inscribed angle is half the measure of the arc intercept.
In other words, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.
Hence, lets find the value of x in the angle ABC.
Therefore,
m∠ABC = 1 / 2 (arc AC)
arc AC = 76 degrees.
Hence,
m∠ABC = 1 / 2 × 76
2x - 12 = 1 / 2 × 76
2x - 12 = 38
add 12 to both sides of the equation
2x - 12 = 38
2x - 12 + 12 = 38 + 12
2x = 50
divide both sides by 2
2x / 2 = 50 / 2
x = 25
