arcAE = 126°

Step-by-step explanation:

Note that arcAD is a diameter therefore arcAD = 180°. And arcAD = arcAE + arcED

Also note that the inscribed angleEAD intercepts the arcED and according to the inscribed angle theorem,

angleEAD = (1/2)arcED

or

arcED = 2×angleEAD = 2×(27°) = 54°

This means that the arcAE is

arcAE = arcAD - arcED

= 180° - 54°

= 126°

B = 57°, b = 26 cm. Find c in cm. Round to 2 decimal places.​
baherus [9]

Answer:

17

Step-by-step explanation:

Answer:

21.1cm

Step-by-step explanation:

From sine rule which can be expressed as

b/ sinB = c/sin C

B = 57°,

b = 26 cm.

FROM THE COMPLETE QUESTION,

C=43°

Then we can substitute this

26/sin(57) = c/sin(43)

If we cross multiply and make "c" subject of the formula

c=[26 × sin(43)]/ sin57

c= 21.1 cm

HELP!! joels apartment building is 42 ft tall and casts a shadow of 20ft. If Joel is 6 ft tall, how long is his shadow
zhenek [66]

Step-by-step explanation:

an object and its shadow create a right-angled triangle.

2 objects and their shadows create 2 similar right-angled triangles.

that means the angles are the same, and the side lengths of one triangle all correlate with the corresponding side lengths of the other triangle via the same factor.

so,

42 × f = 6

f = 6/42 = 1/7

the length of Joel's shadow is then

20 × f = 20 × 1/7 = 2.857142857... ft
