Question

Помогите пожалуйста!!!!!!!!

Answer 1

13:

<Т = 360-90-130-90 = 50 гр.

<TSP = <TPS => <TSP = <TPS = 1/2*(180 - <T) = 65 гр.

14:

<ABE = 90-65 = 25 гр.

<ACB = 180-65-53 = 62 гр.

<EBC = 90-62 = 28 гр.

<DCB = 90-53 = 37 гр.

<CMB = 180 - <DCB - <EBC = 180-37-28 = 115 гр.

17:

PS/SR = ½ => < PRS = 30 гр.

<PRQ = 2 * <PRS = 60 гр. => <PQR = 90-60 = 30 гр. => <RQT = 180-30 = 150 гр.

<SRQ = <SQR => SR = SQ = 15.6

18:

MR = RN

P(MKR) = MK+KR+MR = MK+KR+RN = MK+KN

32 = MK+26

MK = 6
