So I took the test and my teacher said to label all of the degrees so

angle 1,3,5,7,9,11,13,15 all = 95 degrees

angle 2,4,6,8,10,12,14,16 all = 85 degrees

I know 1 and 3 are vertical angles

3 and 8 are same side interior angle

4 and 14 alternate interior angles

6 and 12 are alternate exterior angles

13 and 9 are corresponding angles

4 and 7 are same side interior angles

I believe these are correct but you might want to double check with some other source

Lillian and Jacob work at a dry cleaners ironing shirts. Lillian can iron 25 shirts per hour, and Jacob can iron 20 shirts per h

vladimir1956 [14]

Answer:

Lillian worked 7h and Jacob worked 6h

Step-by-step explanation:

the number of hours Lillian worked are x (h)

the number of hours Jacob worked are y (h)

(0 < x,y < 13)

=> Lilian ironed: 25x (shirts)

Jacob ỉroned: 20y (shirts)

because Lillian and Jacob worked a combined 13 hours and ironed 295 shirts, we have:

$\left \{ {{x+y=13} \atop {25x+20y=295}} \right. => \left \{ {{x=7} \atop {y=6}} \right.$

so Lillian worked 7h and Jacob worked 6h

What type of triangle is triangle ABC give reasons for your answer help please I need 1 more mark But I don't know what I'm doin

ladessa [460]

Answer: isosceles

Step-by-step explanation:

By the alternate interior angles theorem, $\angle CAB=50^{\circ}$

Since angles in a triangle add to 180 degrees, $\angle ACB=180^{\circ}-80^{\circ}-50^{\circ}=50^{\circ}$

Since sides opposite equal angles in a triangle are equal, $AB=BC$ .

So, triangle ABC is <u>isosceles</u>
