Area of a triangle = $\frac{1}{2}$ · base x height
   180 = $\frac{1}{2}$ · base x 40
   180 = 20 · base
      9 = base

Pythagorean Theorem:
base² + height² = hypotenuse²
9²    + 40² = hypotenuse²
81 + 1600 = hypotenuse²
1681    = hypotenuse²
   √1681           = √hypotenuse²
   41    = hypotenuse

Answer: the length of the hypotenuse is 41 m

Assume lines p and q intersect to form adjacent angles 1 and 2.

frosja888 [35]

Answer:

x=12

Step-by-step explanation:

To make these 2 lines perpendicular to each other, one of their angles must be equal to 90 degrees.

Therefore, we can set up an equation with one of the angles:

7x+6=90

7x=84

x=12

The information of the other angle is useless in this case, but we can use it to check by plugging in 12 for x, and seeing if it equals to 90:

8*12-6=96-6=90

Therefore, x=12.

Help me please cant figure it out<br> D;

Juli2301 [7.4K]

supplementary angles sum up to 180°, so let's say we have two angles, a and b, a + b = 180, but we know that a is <u>twice the measure of her partner</u>, so a = 2b.

$\bf a+b=180\implies \stackrel{a}{2b}+b=180\implies 3b=180\implies b=\cfrac{180}{3} \\\\\\ \boxed{b=60}~\hspace{5em}a=2b\implies a=2(60)\implies \blacktriangleright a=120 \blacktriangleleft$

90% chance that it's not yellow

Step-by-step explanation:

Since there is 1 yellow that mean that 9/10 marbles are a different color
