Step-by-step explanation:
we know that:
[tex]tan(x - y) = \frac{tanx - tany}{1 + tanx \times tany} [/tex]
using this, we can see that x = 73 and y = 13
using this, tan(x-y) = tan(73-13) = tan(60)
therefore, A = 60
we know that tan(60) = √3
therefore, B = 3

Answers
Answer:
P = 173.6 mSteps:
given:
A = 235.2 m²
S1 = 2.8 m
S2 = A/S1
S2 = 235.2/2.8
S2 = 84 m
P = 2(S1+S2)
P = 2(2.8+84)
P = 2 × 86.8
P = 173.6 m

By the property of triangle,
If the sides of triangle are unequal, then the ratio of the measures of the angles will be equal to the ratio of their opposite sides.
Following this rule,
Angle opposite to the largest side will be biggest and angle opposite to the smallest side will be smallest.
Since, LJ > KL > JK
Therefore,
∠K > ∠J > ∠L

A washer and a dryer cost $726 combined. The washer costs $76 more than the dryer. What is the cost of the dryer?
Answers
Answer:Cost of dryer=$325
Step-by-step explanation:
Let the dryer be represented as x
and the washer be x+76
such that the price of both can be written as
dryer + washer=$726
x + x+76=726
2x+76=726
2x=726-76
2x=650
x=650/2=325
Cost of dryer =x=$325

Could someone help me find an equation ❤️
Answers
Answer:
-(2/3)x+4
Step-by-step explanation:
For the slope you do rise over run, since the graph intercepts the y-axis at 4 and goes down to 0 the rise is -4 and from the same point the graph "runs" 6 the rise/run is -4/6 which can be simplified to -2/3. For the y-intercept you simply find where the graph touches the y-intercept and add (or subtract if the number is negative) that to the end of the equation.
