Answer:

x = 75°

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

Therefore,

78° + 27° + x° = 180°

Add like terms

105 + x = 180

105 + x - 105 = 180 - 105 (substraction property of equality)

x = 75°

Talja [164]

Answer:

Four less than an unknown value E) y-4

Quotient of a variable and four B) \frac{z}{4}

Some number to the power of four A) a^4

Four times an unknown value D) 4x

Four more than some number C) b+4

Step-by-step explanation:

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling y the unknown value, it means we have to write

y-4

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling z the unknown variabl, it means we have to write

\frac{z}{4}

- Some number to the power of four --> this means that we have to write the power of a number, in the form a^m, where m in this case is equal to 4. Calling a the unknown number, it means we have to write

a^4

- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling x our unknown values, we have to write

4x

- Four more than some number --> this means we have to add 4 to an unknown number. Calling b the unknown number, it means we have to write

b+4
