<h2><u>Angles</u> </h2>
<h3>Hintunglah nilai x</h3>
Seperti yang anda lihat dalam rajah, kedua-dua sudut membentuk pasangan linear. Untuk menyelesaikan x, samakan dua ukuran sudut yang diberikan kepada 180.
<u>Diberi:</u>
20 + 6x°
4x°
<u>Penyelesaian:</u>
- 20 + 6x + 4x = 180
- 20 + 10x = 180
- 10x = 180 - 20
- 10x = 160
- x = 160/10
- x = 16
Buktikan bahawa kedua-dua sudut adalah pasangan linear:
- 20 + 6x + 4x = 180; x = 16
- 20 + 6(16) + 4(16) = 180
- 20 + 96 + 64 = 180
- 116 + 64 = 180
- 180 = 180
<u>Jawab:</u>
- Oleh itu, nilai x ialah <u>16</u>.

Answer:
OD) 4.9 units, 14.2 units
<em> The lengths of the legs of a right triangle</em>
<em> </em>a = 4.9units , b = 14.2units and hypotenuse 'c' = 15
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the Acute angle is 19°
And hypotenuse (AC ) = c= 15
We will take cos∝ =
⇒
⇒ BC = 15 × cos 19°
⇒ BC = 15 ×0.9455
⇒ BC = 14.18
The length of the one leg of the right angle triangle
BC = b = 14.18≅ 14.2
We know that ΔABC is a right angle triangle
a² = c² - b²
= 15² - (14.18)²
= 225 - 201.07
= 23.93
a² = 23.93
a = √23.93 = 4.89≅4.9
<u><em>Final answer:-</em></u>
<em> The lengths of the legs of a right triangle</em>
<em> </em>a = 4.9units , b = 14.2units and hypotenuse 'c' = 15
I believe it would be 13+13+13+13=52 because all side of a square are equal
Answer:
Step-by-step explanation:
Given:
AP = 3,
PQ = 5,
QB = 7,
CP = 2,
QD = 14
Required:
1. PD
2. EQ
SOLUTION:
1. Based on Intersecting Chords Theorem,
AP = 3
PB = PQ + QB = 5 + 7 = 12
CP = 2
PD = ?
Plug in the values into the equation
Divide both sides by 2
b. Based on Intersecting Chords Theorem,
EQ = ?
QD = 14
AQ = AP + PQ = 3 + 5 = 8
QB = 7
Plug in the values into the equation
Divide both sides by 14
