I think it’s 70 degrees

Answer:

61 degrees

Step-by-step explanation:

Hi, so the angles will add up to 360.

So all you need to do is take 360, and subtract 210 and 89 from it.

So:

360 - 210 - 89 = 61

I hope this helps!

Josh's death is 36 in tall,when he measured the desk using a yard stick, it was 1 yard tall. Why did the number decrease when he

UkoKoshka [18]

Explanation:

A yard is a larger unit of measure than an inch, so it takes fewer yards to equal the distance of a larger number of inches.

As it happens, 1 yard is exactly the same as 36 inches (by definition). So the measurement that is 36 inches will be a measurement that is 1 yard.

Square pyramid is made up of a base with a side length of 10 inches and faces that are triangles with a height of 12 inches what

Nataly [62]

The surface area of the square pyramid is 360 in²

Explanation:

Given that the side length is 10 inches.

The height of the pyramid is 12 inches.

We need to determine the surface area of the pyramid.

The surface area of the pyramid is given by

$SA=s^2+2sl$

Where s is the side length and l is the slant height.

The slant height can be determined using the formula,

$l=\sqrt{h^2+b^2}$

where h = 12 and $b=\frac{s}{2} =5$

Substituting these values in the formula, we get,

$l=\sqrt{12^2+5^2}$

$=\sqrt{144+25}$

$l=\sqrt{169}$

$l=13$

Thus, the slant height is $l=13$

Now, we shall find the surface area of the pyramid.

Substituting $l=13$ and $s=10$ in the formula $SA=s^2+2sl$ , we get,

$SA=10^2+2(10)(13)$

$=100+260$

$SA=360 \ in^2$

Thus, the surface area of the square pyramid is 360 in²

How many solutions does each equation below have? how can you tell?

Vikki [24]

A) This one has no solutions because the answer of the equation is 0=-1 which isn't true.

b) 6t-3=3t+6 ==> 3t=9 ==> t=3 This means that this has one solution.

c) 6 (2m-3)-3m=2m-18+m ==> 12m-18=2m-18+m ==> 9m=0 ==> m=0 so this one has no solutions.

d) 10+3y-2=4y-y+8 ==> 8+3y=3y+8 ==> 0=0 ==> Infinitely many solutions.

~Hope I helped!~
