Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>30</u></em></h2>
Step-by-step explanation:
<em><u>According</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>figure</u></em><em><u>, </u></em>
54° + 3x+36° = 180° <em>[</em><em>Linear</em><em> </em><em>pair</em><em>]</em>
=> 3x + 90 = 180
=> 3x = 180 - 90
=> 3x = 90
=> <em><u>x = 30 (Ans)</u></em>
Answer:
x = 2 and y = 1.
Step-by-step explanation:
If in the given quadrilateral all angles ∠A, ∠B, ∠C, ∠D are 90°and opposite sides are equal, then this property of a quadrilateral concludes that the given quadrilateral is a rectangle.
5x - 4 = 2y + 4
5x - 2y = 4+4 =8--------(1)
and 5y + 1 = 3x
3x - 5y = 1--------(2)
We multiply equation 1 by 3 and equation 2 by 5
15x - 6y = 24------(3)
15x - 25y = 5------(4)
Now we subtract equation 4 from 3
15x - 6y - (15x - 25 y) = 24-5
15x -6y -15x + 25y =19
19y = 19
y = 1
By putting y = 1 in equation 1.
5x - 2 = 8
5x = 10
x = 2
Answer:
q = 2
Step-by-step explanation:
0.5-0.125q=(q-1)/4
At first, we have to multiply both the sides by 4.
4 × (0.5 - 0.125q) = q - 1
or, 2 - 0.5q = q - 1
now, we change the side by taking constant into the right side and the number into the left side.
2 + 1 = q + 0.5q
or, 3 = q (1 + 0.5)
or, 3 = 1.5 q
or, 1.5 q = 3
or, 
= (3 ÷ 1.5) [Dividing both the sides by 1.5]
or, q = 2
Therefore, q = 2
Answer:
6.5%
Step-by-step explanation:
Percentage error formula =
|Estimated value - Real value|/Real value × 100
From the above question,
Estimated value = 17,466
Real value = 16,400
Percentage error = |17,466 - 16,400|/16,400 × 100
= 1066/16,400 × 100
= 0.065 × 100
= 6.5%
Therefore, the percent error = 6.5%
