For the first picture using Pythagorean Theorem, we know that a^2 + b ^2 = c^2 but since we only know c ( 99.2) and b ( 62 ) we need to use the theorem to find a the equation we use for that is :
A = square root of ( c^2 - B^2 )
A = 77.44
Answer:
x=12
Step by step explanation:
Step by step explanation:Add 9 to both sides :
15 = 2x - 9
15 + 9 = 2x - 9 + 9
Simplify:
24 = 2x
Divide both sides to get the result:
24 = 2x
24/2 = (2x)/2
Result:
x=12
Answer:
h(g(n))=4n-9
Step-by-step explanation:
h(g(n))=4*g(n)-5 ( we replace n in the formule of h(n) by g(n).
h(g(n))=4(n-1)-5
h(g(n))=4n-4-5
h(g(n))=4n-9
Hope you understand it
Answer:
#1)
Angle A = 30 degrees; 180 - 150 = 30
Angle B = 120 degrees; 180 - 60 = 120
#2)
Angle A = 65 degrees; 180 - 115 = 65
Angle B = 25 degrees; 180 - 155 = 25
