Answer:

-8

Step-by-step explanation:

All triangle angles must add up to 180.

If we look at the triangle, it has the angles of 40 degrees, and a right angle (90). If we add those together, we get 130.

So that means the top angle must be 50 degrees. Because 40+50+90=180.

So if the top angle is 50, the the other side must be 130. Again, because that is a 180 degree angle, going straight up.

So if we need to get 130, and the answers are not -4 or 3. Then the answer must be -8. Because 138+(-8)=130. Boom.

Hope this helped in some way. Stay safe, and have a good day!

Find the area to the right of the z-score 1.39 and to the left of the z-score 1.53 under the standard normal curve.1.2 1.3 1.4 0
svetoff [14.1K]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is  P( 1.39 <  z <  1.53 ) = 0.0193

Step-by-step explanation:

From the question we are told to obtain the area to the of the z-score 1.39 and to the left of the z-score 1.53, this is mathematically represented as

        P( 1.39 <  z <  1.53 ) =  P( z <  1.53 ) - P( z <  1.39 )

From the z table on the question the area under the normal curve to the left corresponding to 1.53 and  1.39  is

       P( z <  1.53 )  = 0.9370

and

      P( z <  1.39 )  = 0.9177

So

     P( 1.39 <  z <  1.53 ) = 0.9370 - 0.9177

=>  P( 1.39 <  z <  1.53 ) = 0.0193

In ΔIJK, i = 180 cm, ∠J=89° and ∠K=38°. Find the length of k, to the nearest 10th of a centimeter.
vodka [1.7K]

Answer:

138.8 cm

Step-by-step explanation:

Angle I =180 - 89 - 38 = 53

Using sine law

i/sinI = k/sinK

180/sin53 = k/sin38

k = 138.76

In the figure below, BD and EC are diameters of circle P. What is the arc measure of AE in degrees?
Snowcat [4.5K]

Answer:

27°

Step-by-step explanation:

Since BD is a diameter then arc BD = 180°

∠ APE = 180° - (90 + 63)° = 180° - 153° = 27°

The measure of the arc AE is equal to the angle at the centre subtended by it.

arc AE = ∠ APE = 27°
