Solve the right triangle. Round decimal answers to the nearest tenth.

Mathematics
1 answer:
AnnZ [28]3 years ago
5 0

Answer:

See solution below

Step-by-step explanation:

According to pythagoras theorem

hyp^2 = opp^2 + adj^2

10^2 = 4^2 + b^2

100 = 16 + b^2

b^2 = 100-16

b^2 = 84

b = √84

b ≈ 9

Using SOH CHA TOA identity

sin B = AC/AB

Sin B = 9/10

B = arcsin0.9

B ≈ 64degrees

sinA = BC/AB

Sin A = 4/10

A = arcsin0.4

A ≈ 24degrees

Find the m∠RQP of the triangle
dmitriy555 [2]

Step-by-step explanation:

in the given figure ,

the two sides of the triangle are equal , so their opposite angles are equal .

so , we get

=》Angle RPQ = Angle PRQ = 65°

and some of interior angels of the triangle measures 180°

so,

=》RPQ + PRQ + RQP = 180°

=》65° + 65° + RQP = 180°

(Because RPQ = PRQ = 65°)

=》130° + RQP = 180°

=》RQP = 50°

For each of these relations on the set {21, 22, 23, 24}, decide whether it is reflexive, whether it is symmetric, whether it is
bonufazy [111]

Answer:

Step-by-step explanation:

I. { (22,22) , (22,23) , (22,24) , (23,22) , (23,23) , (23,24) }

Reflexive : True because we see the pairs (22,22) , (23,23)..

Symmetrix : NO, as we see the pairs (22,24) BUT NOT (24,22)

Transitive : YES, As we see (22,22 ) and (22, 24) , we see the pairs (22,24)

Antisymmetric : NO

II){ (21,21) , (21,22) , (22,21) , (22,22) , (23,23) , (24,24) }

Reflexive : True because we see the pairs (22,22) , (23,23) (21,21)

Symmetrix : Yes, as we see the pairs (21,22) AND (22,21)

Transitive : YES,

Antisymmetric : NO
