What is the answer to this

stealth61 [152]

Hello!

The angle is a right angle, which measures 90°.

3x + x = 4x

Angle = 4x + 10 = 90

Switch that around

90 - 10 = 4x

90 - 10 = 80

80 = 4x

Divide by 4

$\frac{80}{4} = \frac{4x}{4}$ ]

$\framebox{x = 20 \°}$

Can anyone help me with this? i don’t understand it, thank you.

Alina [70]

Answer:

Step-by-step explanation:

It is done by Middle term splitting.

Taking the general equation ax² + bx + c, by middle term splitting, "b" should be splitted such that the numbers either on adding or on subtracting must be equal to "b" and their products must be equal to "a x c".

For example, in the question it's already given that the equation 8x² + bx + c is middle term splitted into 8x² + px + qx + 3.

So, that means "p x q" must be equal to "8 x 3", i.e., 24.

Hope it helps :)

(a) The total cost, C, is given by:

$C(t)=3+0.5t$

b) With 3 ounces of toppings, we have

$t=3$ $C(3)=3+0.5(3)=3+1.5=4.5$

Hence Evan's ice cream would cost $4.50
