Step-by-step explanation:
25
The diagonals of a kite are perpendicular to each other, hence
∠EHF = 90°
The sum of the 3 angles in a triangle = 180°
In ΔEHF
∠1 + ∠2 + 90 = 180, that is
42 + ∠2 + 90 = 180
132 + ∠2 = 180 ( subtract 132 from both sides )
∠2 = 48°
26
DE and DG are congruent sides, hence
4x - 2 = 22.5 ( add 2 to both sides )
4x = 24.5 ( divide both sides by 4 )
x = 6.125
27
∠A and ∠C are congruent, hence
∠A = ∠C = 82°
The sum of the interior angles of a kite = 360°, hence
x = 360 - (82 + 82 + 140) = 360 - 304 = 56
25). Measure of angle 2 will be 48°.
26). Value of x = 6.125
27). Value of x = 56°
Properties of a kite,
- Two pairs of the adjacent sides of kite are equal.
- Diagonals of a kite intersect each other at 90°.
- One pair of opposite angles are equal.
25). Given in the picture,
- DEFG is a kite having diagonals EG and DF perpendicular.
- m∠1 = 42°
Apply triangle sum theorem in ΔEHF,
m∠EHF + m∠2 + m∠1 = 180°
90° + m∠2 + 42° = 180° [Since, m∠EHF = 90°]
m∠2 = 180° - 132°
m∠2 = 48°
Therefore, measure of angle 2 will be 48°.
26). Given in the question,
- DE = 4x - 2 and DG = 22.5
By the property of a kite,
DE = DG
(4x - 2) = 22.5
4x = 24.5
x = 6.125
Therefore, value of x will be 6.125
27). Given in the question,
- Kite ABCD with m∠B = 140°, m∠C = 82°, m∠D = x°
Sum of the interior angles of a kite = 360°
Therefore, m∠A + m∠B + m∠C + m∠D = 360°
By the property of a kite,
m∠A = m∠C = 82°
m∠A + m∠B + m∠A + m∠D = 360°
2(m∠A) + m∠B + m∠D = 360°
2(82°) + 140° + x° = 360°
x = 360° - 304°
x = 56°
Therefore, value of 'x' will be 56°.
