The unlabeled part of the right angle is complementary to 68 degrees, so 22 degrees. y is supplementary to 78 degrees, so 102 degrees.  z as the third angle in the small triangle is 180 less than the sum of the other two,

z = 180 - 22 - 102

Answer: 56 degrees

Answer:

56 degrees.

Step-by-step explanation:

x = 180 - (68+78)

=  34 degrees  ( as there are 180 degrees in a triangle).

Consider the large right-angled triangle:

z = 180 - (90 + x)

= 180 - (90 + 34)

= 180 - 124

= 56 degrees.

Translate the figure 5 units up. Then decide if each statement about translated figures is true or false,
m_a_m_a [10]

Answer:

First, second, and third are true.

Fourth is false.

Step-by-step explanation:

1. When we're translating a figure, everything about the figure stays the same except its location on the coordinate plane. The side lengths, the angle measures, and parallel sides will not change.

2. The fourth one is false because two figures/objects are congruent if they have the same shape and size. Since translation only affects the location on a coordinate plane, the original and final figure are congruent.

Given the function f(x)=-2x^2+4x-7, find f(-4)
jeka57 [31]
Let's begin by evaluating f(x) using the value of 3:    f(x) = 2x2 - 4x - 4 (original function)    f(3) = 2(3)2 - 4(3) - 4 (plugging in 3 for x)    f(3) = 2 (computed result) Now let's evaluate g(x) using the value of 3:    g(x) = 4x - 7 (original function)    g(x) = 4(3) - 7 (plugging in 3 for x)    g(x) = 5 (computed result) Finally, we'll sum our results:    (f + g)(3) = 2 + 3 (add f(3) and g(3))    <span>(f + g)(3) = 5 (final answer)</span>

Answer:

Total = 104\ hrs

Step-by-step explanation:

Given

Monday = 15\ hrs

Tuesday = 13\ hrs

Wednesday = 24\ hrs

Required

Determine the hours of practice over 6 days

First, we calculate the hours for the given 3 days.

Hours = Monday + Tuesday + Wednesday

Hours = 15\ hrs + 13\ hrs + 24\ hrs

Hours = 52\ hrs

The hours of practice for the other three days is also 52 hours.

So, the total is:

Total = 52\ hrs + 52\ hrs

Total = 104\ hrs
