Answer:

They are both correct

Step-by-step explanation:

tan A = opposite / adjacent = 3/4   >>> A= 36.9 deg

tan C = opposite / adjacent = 4/3   >>> C= 53.1 deg

cheak:

<B+ <A + <C = 180 deg

90 + 36.9 + 53.1 = 180

180 = 180

Answer:

Botn are correct

Step-by-step explanation:

Tan ratio can be obtained by opposite/adjacent

Both students are correct. They have different values only because they have taken different reference angles

Rhianna has taken angle A as the reference angle,

So tanA = opposite/adjacent = BC/AB

tanA = 3/4

Christopher has taken angle C as the reference angle,

So tanC = opposite/adjacent = AB/BC

tanC = 4/3

In the diagram triangles ABE and ACD are similar.
jolli1 [7]

Answer:

p = 7.2

q = 6.4

Step-by-step explanation:

if the triangles are similar then the side lengths must be proportional :

AC/BA = CD/BE

9/5 = p/4 cross multiply expressions

5p = 36 divide both sides by 5

p = 7.2

same goes for q

9/5 = (q+8)/8 cross multiply expressions

72 = 5(q+8) divide both sides by 5

14.4 = q+8 subtract 8 from both sides

6.4 = q

You have invested in three different stocks: Engineering Aces, Upton Clothiers, and Thompson Musical Instruments. Because you ha
Serga [27]

Answer:

answer is 0.001254.

Step-by-step explanation:

Given that you invested in 3 stocks of Engineering Aces, Upton Clothiers, and Thompson Musical Instruments.

Also given that each stock value is independent of the other.

Let E be the event changing in value by more than 10% in a given week for Engineering Aces,

U be the event changing in value by more than 10% in a given week for Upton Clothiers, and T be the event changing in value by more than 10% in a given week for Thompson Musical Instruments.

Given that P(E) =  = 19%

P(U) = 11%

P(T) = 6%

probability that all three will change by more than 10% in the same week

= P(EUT)

= P(E) P(U) P(T) since three events are independent.

=0.19(0.11)0.06

= 0.001254
