I’m literally dumb pls help me

Mathematics
1 answer:
Verdich [7]3 years ago
7 0

Answer:

32.4 ft

Step-by-step explanation:

the perimeter of the half circle = ( 1/2 * 3.1 * 8) - 8 = 4.4 ft

the total perimeter = 10 + 8 +10 + 4.4 = 32.4 ft

( the right-side width of the rectangle is the diameter of the circle because it passes the origin point. Then you just need to calculate the perimeter of that half circle. Remebering to subtract the length of that diameter because it is not included in the total diameter.)

If angle ABD is 90 degrees. Select all of the angles that measure 42 degrees.
m_a_m_a [10]

Answer:

Measure of angle 2 and angle 4 is 42°.

Step-by-step explanation:

From the figure attached,

m∠ABC = 42°

m(∠ABD) = 90°

m(∠ABD) = m(∠ABC) + m(∠DBC)

90° = 43° + m(∠DBC)

m(∠DBC) = 90 - 43 = 47°

Since ∠ABC ≅ ∠4 [Vertical angles]

m∠ABC = m∠4 = 42°

Since, m∠3 + m∠4 = 90° [Complimentary angles]

m∠3 + 42° = 90°

m∠3 = 90° - 42°

        = 48°

Since, ∠5 ≅ ∠3 [Vertical angles]

m∠5 = m∠3 = 48°

m∠3 + m∠2 = 90° [given that m∠2 + m∠3 = 90°]

m∠2 + 48° = 90°

m∠2 = 90 - 48 = 42°

m∠3+ m∠4 = 90° [Since, ∠3 and ∠4 are the complimentary angles]

48° + m∠4 = 90°

m∠4 = 90 - 48 = 42°

Therefore, ∠2 and ∠4 measure 42°.
