Solve for the right triangle given only one side and angle
Answers
Answer:
CD = √11 and CE = √11
Step-by-step explanation:
We know that m∠D is 45° (by using the sum of interior angles in a triangle) so therefore, ΔDCE is a 45 - 45 - 90 triangle (the 45, 45, and 90 refer to the angle measures). The ratio of sides in a 45 - 45 - 90 triangle is 1 : 1 : √2 where the 1s are the sides and the √2 is the hypotenuse. We need to solve for x in x : x : √22. If you notice that √22 = √2 * √11, we can use this to find x, therefore, x = 1 * √11 = √11 so CD = √11 and CE = √11.
Answer:
Step-by-step explanation:
The triangle is a right triangle.
We can apply trigonometric functions to solve for the missing sides.
sin θ = opp/hyp
sin 45 = CD /√22
Multiply both sides by √22.
√22 sin 45 = CD
√11 = CD
cos θ = adj/hyp
cos 45 = CE /√22
Multiply both sides by √22.
√22 cos 45 = CE
√11 = CE

The equation of the line x + 2y = 6 in slope-intercept form is y = - (1/2)x + 6.
What is slope?
The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is its graph or the rate of change is large.
The equation of the given line is x + 2y = 6.
We know equation of a line in slope intercept form is,
y = mx + b.
Therefore,
x + 2y = 6.
2y = - x + 6.
y = - (1/2)x + 6.

0.2, 0.05, 0.48, 0.6
0.2, 0.48, 0.05, 0.6
0.05, 0.2, 0.6, 0.48
Answers
Answer:
0.05, 0.2, 0.48, 0.6.
Step-by-step explanation:
Given : Numbers .
To find : Which of the following lists is in order from smallest to largest.
Solution : We have given number 0.05, 0.48, 0.2, 0.6
We need to arrange in order to smallest to largest.
We can see 0.05 is the smallest because it is on the hundredth place .
0.2 is on tenth place
0.48 is on 4 number on tenth place
0.6 is on tenth place with largest values .
So, the numbers smallest to largest 0.05, 0.2, 0.48, 0.6.
Therefore, 0.05, 0.2, 0.48, 0.6.
=> 0.05, 0.2, 0.48, 0.6 is the answer,
If QR = 20 in., RS = 7 in., and SQ = 24 in., what is PN?
3 in.
7 in.
20 in.
24 in.
Answers
Answer: PN= 20 in.
Step-by-step explanation:
Given: In triangles PMN and QSR :
Length of P N ≅ Length of RQ (1) [ '≅' → Sign of congruence]
Length of QS ≅ Length of PM
Length of MN ≅ Length of RS
By SSS congruence rule
ΔPMN ≅ ΔQSR
Since Length of QR =20 in. [Given]
From (1)
Length of PN= 20 in. [Congruent means exactly equal]
