Answer:

B=59.58

B'==120.42

Step-by-step explanation:

For the larger triangle, by sin rule, sinB/10=sin45/8.2

sinB=10*sin45/8.2

For the small triangle on the left hand side, by sin rule, sinB'/10=sin45/8.2

sinB'=10*sin45/8.2

So sinB=sinB' but as B'>90, B and B' are supplementary

B=sin^-1(10*sin45/8.2)=sin^-1(0.8623)=59.58

B'=180-B=180-59.58=120.42

Answer:

Step-by-step explanation:

apply sine rule 2 the triangle on left:

sinB'/10=sin45deg/8.2

sinB'=10*sin45deg/8.2=0.8623

B'=59.58deg or 120.42deg

as shown in the pic, B' > 90deg.

so B'=120.42deg.

the triangle on right has 2 sides at 8.2 so it is isosceles

B=adjacent < of B'

=180-120.42

=59.58deg

If 2/3 + p = 1 and 4/5+ q = 3, what is the value of p+q?
inessss [21]

Answer:

p+q = 38/15

Step-by-step explanation:

2/3+p = 1. p = 1 - 2/3

4/5 + q = 3. q = 3 - 4/5

p + q = 1 - 2/3 + 3 - 4/5

-2/3 - 4/5 (common denominator = 15)

4 - 10/15 - 12/15 = 4 - 22/15

4 - 22/15 = (4*15 - 22)/15

= 38/15
