Answer:
Value of angle A is 83.
solution,
I) x°+x°+15+2x°+1=180(Sum of angle of triangle)
or,4x+16=180
or,4x=180-16
or x=164/4
.°.x=41
Again
Angle A = 2x°+1 = 2×41 + 1 =83.
Answer:
6.24 feet (to nearest hundredth)
Step-by-step explanation:
Use the Pythagoras Theorem:-
20^2 = x^2 + 19^2 where x = height of the loading dock.
x^2 = 20^2 - 19^2 = 39
x = √39
= 6.2449 feet
Answer:
248
Step-by-step explanation:
If 4/10 of visits result in medication being prescribed, then 4/10 of 620 visits would be expected to have that result:
4/10 × 620 = 4×62 = 248
About 248 visits would be expected to result in medication being prescribed.
Answer: x=−5 or x=5
Step-by-step explanation:
−3x4+27x2+1200=0
Step 1: Factor left side of equation.
−3(x2+16)(x+5)(x−5)=0
Step 2: Set factors equal to 0.
x2+16=0 or x+5=0 or x−5=0
x=−5 or x=5
