The measures of the angles of a triangle are (3x – 100)°, (x – 10)°, and (x – 10)°.

statuscvo [17]

Answer:

x = 60

largest angle = 80°

Step-by-step explanation:

the sum of all three angles in a triangle = 180°

(3x - 100) + (x - 10) + (x - 10) = 180

simplify:

5x = 300

x = 60

angles are 80°, 50°, and 50°

lara [203]

Answer: Hardwood flooring

Step-by-step explanation:

Given

Rohann renovation of Carpentering cost $875 for $20\ m^2$

For hardwood flooring $17\ m^2$ cost $750

So, cost per square meter for different floors are

$\Rightarrow \text{Carpentering}=\dfrac{875}{20}\\\\\Rightarrow \text{Carpentering}=\$43.75/m^2$

$\Rightarrow \text{Hardwood}=\dfrac{750}{17}\\\\\Rightarrow \text{Hardwood}=\$44.11/m^2$

Thus, the cost of the Hardwood flooring is more expensive.
