Mathematics
1 answer:
Studentka2010 [4]4 years ago
5 0

Answer:

x = 8

Step-by-step explanation:

small triangle is similar to larger one

set up a proportion:  <u>  9  </u>  =  <u> x + 4 </u>

                                  9+12     x+4+2x

<u> 9 </u>  = <u> x+ 4  </u>                  cross-multiply:  9(3x + 4) = 21(x + 4)

21     3x + 4                                            27x + 36 = 21x + 84

                                                              6x + 36 = 84

                                                               6x = 48

                                                               x = 8

What’s the given m ABC = 70 and m ADC = 46
uysha [10]

Answer:

Step-by-step explanation:

Properties of a kite;

1). A kite has one pair of equal angles.

2). A kite has two pairs of adjacent sides.

3). Diagonals of a kite intersect at 90°.

4). Kite has at least one diagonal that bisects the opposite angles.

It's given in the question,

m∠ABC = 70° and m∠ADC = 46°

By the property number -4,

m∠2 = m∠3 = \frac{70}{2} = 35°

m∠8 = m∠9 = \frac{46}{2} = 23°

By the property number - 3,

m∠4 = 90°

By the property of interior angles in a triangle,

m∠3 + m∠4 + m∠5 = 180°

35° + 90° + m∠5 = 180°

125° + m∠5 = 180°

m∠5 = 55°

Similarly, m∠1 + m∠2 + 90° = 180°

m∠1 + 35° + 90° = 180°

m∠1 = 55°

Now m∠6 + 90° + m∠8 = 180°

m∠6 + 90° + 23° = 180°

m∠6 = 180 - 113 = 67°

Therefore, m∠6 = m∠7 = 67°
