Answer:
Height= 8341.6 feet
Step-by-step explanation:
A surveyor determined the height of the new summit by measuring the angle of elevation to the top to be 37°46'. She then moved 1000 feet closer to the volcano and measured the angle of elevation to be 40°30'.
40°30'= 40.5°
37°46'= 37.767°
b = 180-40.5
b= 139.5°
a= 180-139.5-37.767
a= 2.733°
Using sine method
1000/Sina= y/sinB
1000/sin 2.733= y/sin 139.5
(1000*sin 139.5)/sin 2.733= y
(1000*0.6494)/0.04768= y
13619.96= y
Y= 13620 feet
Height/sin 37.767= 13620
Height=13620*sin37.767
Height= 8341.59
Height= 8341.6 feet
The perimeter of a rectangle restaurant kitchen is 40 meters. the area is 96 square meters. what are the dimensions of the kitchen?
Answer:
the way to find triangle is A=1/2
Step-by-step explanation:
This is a bad example but if the arrow has a line underneath you fill in the circle on “-3”
and since X is greater than -3 you shade everything after it
