Solve for b, then solve for each angle in the triangle
lesya692 [45]

We know that the sum of the interior angles of a triangle equals 180, then,in this case we have the following equation:

b+2b+(b+16)=180

then, solving for b, we get:

\begin{gathered} b+2b+(b+16)=180 \\ \Rightarrow4b+16=180 \\ \Rightarrow4b=180-16=164 \\ \Rightarrow b=\frac{164}{4}=41 \\ b=41 \end{gathered}

now that we have that b = 41, we can find the measure of each angle:

\begin{gathered} b=41 \\ 2b=2(41)=82 \\ b+16=41+16=57 \end{gathered}

Given that €1=£0.72 how much is €410 in £ what is the £ to € exchange rate
Virty [35]

Answer:

As per the given statement:

€1 = £0.72

Find how much is €410 in £.

then;

€410 = 0.72 \times 410 = £295.2

Hence, £295.2 much is €410.

to find, the exchange rate of £ to €:

€1 = £0.72

Divide both sides by 0.72 we get;

£1 = €1.389

M∠a=(48−x)°m∠b=(9x−38)°m∠c=90°
Pachacha [2.7K]

<u>The question does not specify the condition that must satisfy the given angles. We assume they are the internal angles of a triangle.</u>

Answer:

<em>x = 10</em>

Step-by-step explanation:

<u>Internal Angles of a Triangle</u>

The measure of the angles of a triangle are given as 48-x, 9x-38, and 90. Since the sum of the internal angles of a triangle is 180°:

48 - x + 9x - 38 + 90 = 180

Simplifying:

100 + 8x = 180

Subtracting 100:

8x = 180 - 100 = 80

x = 80/8

x = 10

timama [110]
To get to cups of raisins you need 8 1/4 cups, and then to get 2/4 you need 2.

So basically you need 10 1/4 cups
