Answer:
Aplha=105
Step-by-step explanation:
The perpendicular looks like double the base hence that angle is 30 and the other triangle have equal perpendicular and base, that angle is 45. So alpha+30+45=180, alpha=105
Answer:
205/6
Step-by-step explanation:
The question simply asks us to plug in 45 minutes into the given equation. In the graph, we see that y-axis is defined to be time. Therefore we set y=45 and solve for x.
45=-6/5x+86
-41=-6/5x (subtract 86 from both sides)
-41*(-5)=-6/5x*(-5) (multiply both sides by -5)
205=6x (divide both sides by 6)
205/6=x
Answer:
44
Step-by-step explanation:
2x² - 2x - 5 = 0 is written in standard form ax^2 + bx + c = 0.
By looking at the formula, we can see that;
a = 2
b = -2
c = -5
Now, we can substitute these variables into the equation we are given and solve.
= b² - 4ac
= -2^2 - 4(2)(-5)
= 4 - 4(-10)
= 4 - (-40)
= 4 + 40
= 44
Best of Luck!
