Answer:50
Step-by-step explanation:(x+10)+(2x+20)=180
3.
The answers 2 and 4 are incorrect because inserting that ad the missing exponent would create only a trinomial.
-9 is incorrect as it would create something more than a polynomial. 7 is incorrect as, if doing a certain type of division, would result in a larger polynomial.
Hope this helps!
Answer:
The measure of angle 4 is 48 degrees.
Step-by-step explanation:
When two angles <u>forming an X</u>
- shape share a common vertex and
- oppose each other
the angle has the same value.
We call this type of angles opposing angles or vertical angles.
Hey there!
Solve using pythagoras theorem (it's given that is triangle is right angled. Pythagoras theorem only works in the case of right triangles) ⇨ Hypotenuse² = Base² + Altitude ²
Here,
Base = 9 mm
Hypotenuse = 15 mm
Altitude = b
Hypotenuse² = Base² + Altitude ²
15² = 9² + b²
225 = 81 + b²
225 - 81 = b²
144 = b²
√144 = b
<u>1</u><u>2</u><u> </u><u>mm </u>= b
Hope it helps ya!
