Plzz help me with the correct ans find x ​
Tresset [83]

Answer:

15

Step-by-step explanation:

Since, triangle ABC is the enlargement of triangle XYZ.

\therefore \triangle ABC \sim \triangle XYZ

So, corresponding sides of both the triangles would be in proportion.

\therefore \frac{x}{6}=\frac{25}{10}

\therefore x= \frac{6\times 25}{10}

\therefore x =\frac{150}{10}

\therefore x = 15

Two negative integers are 8 units apart on the number line and have a product of 308.
Svetach [21]
Calll x the smaller negative number.

The larger number will be x + 8

The product will be x(x+8) = 308

An the equation:

x^2 + 8x = 308
x^2 + 8x - 308 =0

If you solve that equation you will get x = -22 and x = 14.

The result that you are looking is the negative, x = -22.

The larger number is -22 + 8 = -14.

(-22)*(-14) = 308

Answer: x^2 + 8x - 308 =0

What is mZ1?<br> 820<br> 660<br> 1
Tresset [83]

Answer:

∠1 = 148°

Step-by-step explanation:

the triangle interior angles = 180°

the unknown interior angle = 180° - 82° - 66° = 32°

∠1 = 180° - 32° = 148°  because it is supplementary to 32°  (adds together to total 180°)
