You place two wooden support beams under a shelf, as shown. Find the value of x. (3x-13 ) (x- 3) x=
Answers
Answer:
x = 49Step-by-step explanation:
Fins the similar diagram attached;
The sum of the angles is 180 degree since they lie on the same straight line. Hence;
3x - 13 + x - 3 = 180
Collect the like terms;
3x+x -13 - 3 = 180
4x - 16 = 180
4x = 180 + 16
4x = 196
x = 196/4
x = 49
Hence the value of x is 49
Note that the values in question is different from that of diagram but the diagram is similar to what we need

If one of the roots of the equation x²- 4x + k=0exceeds the other by 2, then find the roots and determine the value of k
Answers
Answer:
roots: 1 and 3
k = 3
Step-by-step explanation:
2 roots: p and p+2
(x-p) (x-p-2) = x² - 4x + k
x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k
-2 (p+1) = -4
p+1 = 2
p = 1 ... root 1
p' = 1+2 = 3 ... root 2
k = p² + 2p = 3
check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k

91X + 637 = 273 Find X
pls help?
Answers
Answer:
X = -4
Step-by-step explanation:
91x + 637 =273
First subtract 637 from both sides: 91x = -364
Then, divide both sides by 91 to get X by itself: X = -4
Answer: -4
91x= 273- 637
91x= -364
X= -364/91
X= -4
On a local swim team 6 members each swam 1,685 meters during the season. How many total kilometers did the 6 members swim during the season
Answers
Answer:6 members swam 10.11Km during the season
Step-by-step explanation:
Number of members = 6
meters swam by each of the 6 members = 1,685 meters
Total meters swam by the 6 members during the season
= 1,685 meters X 6
=10,110 meters
But 1000m =1km
10,110 m =10.11Km

Find m ∠ B if mAB = 120° and m ∠ A= 42º.
A)78°
B)80
C)18
D)156
Answers
Answer:
∠B = 78°
Step-by-step explanation:
∠C = 1/2 arc AB = 1/2(120°) = 60° because it is an inscribed angle
∠B = 180° - 42° - 60° = 78°
The measure of ∠ B is 78°.
What is inscribed angle?An inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle subtended at a point on the circle by two given points on the circle.
What is inscribed angle theorem?The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
According to the question
m ∠ A= 42º.
mAB = 120°
By inscribed angle theorem :
mAB = 2 m∠C
120° = 2 m∠C
m∠C = 60°
now,
according to the sum of angle of triangle
m ∠ B + m∠C + m ∠ A = 180°
m ∠ B +60° + 42º= 180°
m ∠ B = 78°
Hence, the measure of ∠ B is 78°.
